+Qualcomm's PM8xxx voltage XOADC
+
+The Qualcomm PM8xxx PMICs contain a HK/XO ADC (Housekeeping/Crystal
+oscillator ADC) encompassing PM8018, PM8038, PM8058 and PM8921.
+
+Required properties:
+
+- compatible: should be one of:
+ "qcom,pm8018-adc"
+ "qcom,pm8038-adc"
+ "qcom,pm8058-adc"
+ "qcom,pm8921-adc"
+
+- reg: should contain the ADC base address in the PMIC, typically
+ 0x197.
+
+- xoadc-ref-supply: should reference a regulator that can supply
+ a reference voltage on demand. The reference voltage may vary
+ with PMIC variant but is typically something like 2.2 or 1.8V.
+
+The following required properties are standard for IO channels, see
+iio-bindings.txt for more details:
+
+- #address-cells: should be set to <1>
+
+- #size-cells: should be set to <0>
+
+- #io-channel-cells: should be set to <1>
+
+- interrupts: should refer to the parent PMIC interrupt controller
+ and reference the proper ADC interrupt.
+
+Required subnodes:
+
+The ADC channels are configured as subnodes of the ADC. Since some of
+them are used for calibrating the ADC, these nodes are compulsory:
+
+adc-channel@c {
+ reg = <0x0c>;
+};
+
+adc-channel@d {
+ reg = <0x0d>;
+};
+
+adc-channel@f {
+ reg = <0x0f>;
+};
+
+These three nodes are used for absolute and ratiometric calibration
+and only need to have these reg values: they are by hardware definition
+1:1 ratio converters that sample 625, 1250 and 0 milliV and create
+an interpolation calibration for all other ADCs.
+
+Optional subnodes: any channels other than channel 0x0c, 0x0d and
+0x0f are optional.
+
+Required channel node properties:
+
+- reg: should contain the hardware channel number in the range
+ 0 .. 0x0f (4 bits). The hardware only supports 16 channels.
+
+Optional channel node properties:
+
+- qcom,decimation:
+ Value type: <u32>
+ Definition: This parameter is used to decrease the ADC sampling rate.
+ Quicker measurements can be made by reducing the decimation ratio.
+ Valid values are 512, 1024, 2048, 4096.
+ If the property is not found, a default value of 512 will be used.
+
+- qcom,ratiometric:
+ Value type: <u32>
+ Definition: Channel calibration type. If this property is specified
+ VADC will use a special voltage references for channel
+ calibration. The available references are specified in the
+ as a u32 value setting (see below) and it is compulsory
+ to also specify this reference if ratiometric calibration
+ is selected.
+
+ If the property is not found, the channel will be
+ calibrated with the 0.625V and 1.25V reference channels, also
+ known as an absolute calibration.
+ The reference voltage pairs when using ratiometric calibration:
+ 0 = XO_IN/XOADC_GND

+Capella Microsystems CM3605
+Ambient Light and Short Distance Proximity Sensor
+
+The CM3605 is an entirely analog part which however require quite a bit of
+software logic to interface a host operating system.
+
+This ALS and proximity sensor was one of the very first deployed in mobile
+handsets, notably it is used in the very first Nexus One Android phone from
+2010.
+
+Required properties:
+- compatible: must be: "capella,cm3605"
+- aset-gpios: GPIO line controlling the ASET line (drive low
+ to activate the ALS, should be flagged GPIO_ACTIVE_LOW)
+- interrupts: the IRQ line (such as a GPIO) that is connected to
+ the POUT (proximity sensor out) line. The edge detection must
+ be set to IRQ_TYPE_EDGE_BOTH so as to detect movements toward
+ and away from the proximity sensor.
+- io-channels: the ADC channel used for converting the voltage from
+ AOUT to a digital representation.
+- io-channel-names: must be "aout"
+
+Optional properties:
+- vdd-supply: regulator supplying VDD power to the component.
+- capella,aset-resistance-ohms: the sensitivity calibration resistance,
+ in Ohms. Valid values are: 50000, 100000, 300000 and 600000,
+ as these are the resistance values that we are supplied with
+ calibration curves for. If not supplied, 100 kOhm will be assumed
+ but it is strongly recommended to supply this.

+ * STMicroelectronics st_lsm6dsx FIFO buffer library driver

+ * LSM6DS3/LSM6DSM: The FIFO buffer can be configured to store data
+ * from gyroscope and accelerometer. Samples are queued without any tag
+ * according to a specific pattern based on 'FIFO data sets' (6 bytes each):
+ * - 1st data set is reserved for gyroscope data
+ * - 2nd data set is reserved for accelerometer data
+ * The FIFO pattern changes depending on the ODRs and decimation factors
+ * assigned to the FIFO data sets. The first sequence of data stored in FIFO
+ * buffer contains the data of all the enabled FIFO data sets
+ * (e.g. Gx, Gy, Gz, Ax, Ay, Az), then data are repeated depending on the
+ * value of the decimation factor and ODR set for each FIFO data set.
+ * FIFO supported modes:
+ * - BYPASS: FIFO disabled
+ * - CONTINUOUS: FIFO enabled. When the buffer is full, the FIFO index
+ * restarts from the beginning and the oldest sample is overwritten

+*****************************************************************************
+
+
+1) Document the device tree node
+
+The downstream tree(the tree that the driver was imported from) at
+http://www.github.com/raspberrypi/linux uses this node:
+
+audio: audio {
+ compatible = "brcm,bcm2835-audio";
+ brcm,pwm-channels = <8>;
+};
+
+Since the driver requires the use of VCHIQ, it may be useful to have a link
+in the device tree to the VCHIQ driver.
+
+2) Gracefully handle the case where VCHIQ is missing from the device tree or
+it has not been initialized yet.
+
+3) Review error handling and remove duplicate code.
+
+4) Cleanup the logging mechanism. The driver should probably be using the
+standard kernel logging mechanisms such as dev_info, dev_dbg, and friends.
+
+5) Fix the remaining checkpatch.pl errors and warnings.

- * This routine takes a FrameTime and derives the difference with-respect

- * ktime based on the difference between the supplied FrameTime and
- * the reference FrameTime.
- *
- * The time difference is calculated to six decimal places. Taking 19.2MHz
- * as an example this means we have 52.083333~ nanoseconds per clock or
- * 52083333~ femtoseconds per clock.
- *
- * Naively taking the count difference and converting to
- * seconds/nanoseconds would quickly see the 0.0833 component produce
- * noticeable errors. For example a time difference of one second would
- * loose 19200000 * 0.08333x nanoseconds or 1.59 seconds.
- *
- * In contrast calculating in femtoseconds the same example of 19200000 *
- * 0.000000083333x nanoseconds per count of error is just 1.59 nanoseconds!
- *
- * Continuing the example of 19.2 MHz we cap the maximum error difference
- * at a worst-case 0.3 microseconds over a potential calculation window of
- * abount 15 seconds, meaning you can convert a FrameTime that is <= 15
- * seconds older/younger than the reference time with a maximum error of
- * 0.2385 useconds. Note 19.2MHz is an example frequency not a requirement.

-This document describes the ACT2000 driver for the
-IBM Active 2000 ISDN card.
-
-There are 3 Types of this card available. A ISA-, MCA-, and PCMCIA-Bus
-Version. Currently, only the ISA-Bus version of the card is supported.
-However MCA and PCMCIA will follow soon.
-
-The ISA-Bus Version uses 8 IO-ports. The base port address has to be set
-manually using the DIP switches.
-
-Setting up the DIP switches for the IBM Active 2000 ISDN card:
-
- Note: S5 and S6 always set off!
-
- S1 S2 S3 S4 Base-port
- on on on on 0x0200 (Factory default)
- off on on on 0x0240
- on off on on 0x0280
- off off on on 0x02c0
- on on off on 0x0300
- off on off on 0x0340
- on off off on 0x0380
- on on on off 0xcfe0
- off on on off 0xcfa0
- on off on off 0xcf60
- off off on off 0xcf20
- on on off off 0xcee0
- off on off off 0xcea0
- on off off off 0xce60
- off off off off Card disabled
-
-IRQ is configured by software. Possible values are:
-
- 3, 5, 7, 10, 11, 12, 15 and none (polled mode)
-
-
-The ACT2000 driver may either be built into the kernel or as a module.
-Initialization depends on how the driver is built:
-
-Driver built into the kernel:
-
- The ACT2000 driver can be configured using the commandline-feature while
- loading the kernel with LILO or LOADLIN. It accepts the following syntax:
-
- act2000=b,p,i[,idstring]
-
- where
-
- b = Bus-Type (1=ISA, 2=MCA, 3=PCMCIA)
- p = portbase (-1 means autoprobe)
- i = Interrupt (-1 means use next free IRQ, 0 means polled mode)
-
- The idstring is an arbitrary string used for referencing the card
- by the actctrl tool later.
-
- Defaults used, when no parameters given at all:
-
- 1,-1,-1,""
-
- which means: Autoprobe for an ISA card, use next free IRQ, let the
- ISDN linklevel fill the IdString (usually "line0" for the first card).
-
- If you like to use more than one card, you can use the program
- "actctrl" from the utility-package to configure additional cards.
-
- Using the "actctrl"-utility, portbase and irq can also be changed
- during runtime. The D-channel protocol is configured by the "dproto"
- option of the "actctrl"-utility after loading the firmware into the
- card's memory using the "actctrl"-utility.
-
-Driver built as module:
-
- The module act2000.o can be configured during modprobe (insmod) by
- appending its parameters to the modprobe resp. insmod commandline.
- The following syntax is accepted:
-
- act_bus=b act_port=p act_irq=i act_id=idstring
-
- where b, p, i and idstring have the same meanings as the parameters
- described for the builtin version above.
-
- Using the "actctrl"-utility, the same features apply to the modularized
- version as to the kernel-builtin one. (i.e. loading of firmware and
- configuring the D-channel protocol)
-
-Loading the firmware into the card:
-
- The firmware is supplied together with the isdn4k-utils package. It
- can be found in the subdirectory act2000/firmware/
-
- Assuming you have installed the utility-package correctly, the firmware
- will be downloaded into the card using the following command:
-
- actctrl -d idstring load /etc/isdn/bip11.btl
-
- where idstring is the Name of the card, given during insmod-time or
- (for kernel-builtin driver) on the kernel commandline. If only one
- ISDN card is used, the -d isdstrin may be omitted.
-
- For further documentation (adding more IBM Active 2000 cards), refer to
- the manpage actctrl.8 which is included in the isdn4k-utils package.

-The ICN driver may be built into the kernel or as a module. Initialization
-depends on how the driver is built:
-
-Driver built into the kernel:
-
- The ICN driver can be configured using the commandline-feature while
- loading the kernel with LILO or LOADLIN. It accepts the following syntax:
-
- icn=p,m[,idstring1[,idstring2]]
-
- where
-
- p = portbase (default: 0x320)
- m = shared memory (default: 0xd0000)
-
- When using the ICN double card (4B), you MUST define TWO idstrings.
- idstring must start with a character! There is no way for the driver
- to distinguish between a 2B and 4B type card. Therefore, by supplying
- TWO idstrings, you tell the driver that you have a 4B installed.
-
- If you like to use more than one card, you can use the program
- "icnctrl" from the utility-package to configure additional cards.
- You need to configure shared memory only once, since the icn-driver
- maps all cards into the same address-space.
-
- Using the "icnctrl"-utility, portbase and shared memory can also be
- changed during runtime.
-
- The D-channel protocol is configured by loading different firmware
- into the card's memory using the "icnctrl"-utility.
-
-
-Driver built as module:
-
- The module icn.o can be configured during "insmod'ing" it by
- appending its parameters to the insmod-commandline. The following
- syntax is accepted:
-
- portbase=p membase=m icn_id=idstring [icn_id2=idstring2]
-
- where p, m, idstring1 and idstring2 have the same meanings as the

-
-Loading the firmware into the card:
-
- The firmware is supplied together with the isdn4k-utils package. It
- can be found in the subdirectory icnctrl/firmware/
-
- There are 3 files:
-
- loadpg.bin - Image of the bootstrap loader.
- pc_1t_ca.bin - Image of firmware for german 1TR6 protocol.
- pc_eu_ca.bin - Image if firmware for EDSS1 (Euro-ISDN) protocol.
-
- Assuming you have installed the utility-package correctly, the firmware
- will be downloaded into the 2B-card using the following command:
-
- icnctrl -d Idstring load /etc/isdn/loadpg.bin /etc/isdn/pc_XX_ca.bin
-
- where XX is either "1t" or "eu", depending on the D-Channel protocol
- used on your S0-bus and Idstring is the Name of the card, given during
- insmod-time or (for kernel-builtin driver) on the kernel commandline.
-
- To load a 4B-card, the same command is used, except a second firmware
- file is appended to the commandline of icnctrl.
-
- -> After downloading firmware, the two LEDs at the back cover of the card
- (ICN-4B: 4 LEDs) must be blinking intermittently now. If a connection
- is up, the corresponding led is lit continuously.
-
- For further documentation (adding more ICN-cards), refer to the manpage

- README file for the PCBIT-D Device Driver.
-------------------------------------------------------------------------------
-
-The PCBIT is a Euro ISDN adapter manufactured in Portugal by Octal and
-developed in cooperation with Portugal Telecom and Inesc.
-The driver interfaces with the standard kernel isdn facilities
-originally developed by Fritz Elfert in the isdn4linux project.
-
-The common versions of the pcbit board require a firmware that is
-distributed (and copyrighted) by the manufacturer. To load this
-firmware you need "pcbitctl" available on the standard isdn4k-utils
-package or in the pcbit package available in:
-
-ftp://ftp.di.fc.ul.pt/pub/systems/Linux/isdn
-
-Known Limitations:
-
-- The board reset procedure is at the moment incorrect and will only
-allow you to load the firmware after a hard reset.
-
-- Only HDLC in B-channels is supported at the moment. There is no
-current support for X.25 in B or D channels nor LAPD in B
-channels. The main reason is that these two other protocol modes have,
-to my knowledge, very little use. If you want to see them implemented
-*do* send me a mail.
-
-- The driver often triggers errors in the board that I and the
-manufacturer believe to be caused by bugs in the firmware. The current
-version includes several procedures for error recovery that should
-allow normal operation. Plans for the future include cooperation with
-the manufacturer in order to solve this problem.
-
-Information/hints/help can be obtained in the linux isdn
-mailing list (isdn4linux@listserv.isdn4linux.de) or directly from me.

-1. Introduction
----------------
-
-The revision 2 Linux driver for SpellCaster ISA ISDN adapters is built
-upon ISDN4Linux available separately or as included in Linux 2.0 and later.
-The driver will support a maximum of 4 adapters in any one system of any
-type including DataCommute/BRI, DataCommute/PRI and TeleCommute/BRI for a
-maximum of 92 channels for host. The driver is supplied as a module in
-source form and needs to be complied before it can be used. It has been
-tested on Linux 2.0.20.
-
-1.1 What Is ISDN4Linux
-
-ISDN4Linux is a driver and set of tools used to access and use ISDN devices
-on a Linux platform in a common and standard way. It supports HDLC and PPP
-protocols and offers channel bundling and MLPPP support. To use ISDN4Linux
-you need to configure your kernel for ISDN support and get the ISDN4Linux
-tool kit from our web site.
-
-ISDN4Linux creates a channel pool from all of the available ISDN channels
-and therefore can function across adapters. When an ISDN4Linux compliant
-driver (such as ours) is loaded, all of the channels go into a pool and
-are used on a first-come first-served basis. In addition, individual
-channels can be specifically bound to particular interfaces.
-
-1.2 What is different between this driver and previous drivers?
-
-The revision 2 driver besides adopting the ISDN4Linux architecture has many
-subtle and not so subtle functional differences from previous releases. These
-include:
- - More efficient shared memory management combined with a simpler
- configuration. All adapters now use only 16Kbytes of shared RAM
- versus between 16K and 64K. New methods for using the shared RAM
- allow us to utilize all of the available RAM on the adapter through
- only one 16K page.
- - Better detection of available upper memory. The probing routines
- have been improved to better detect available shared RAM pages and
- used pages are now locked.
- - Decreased loading time and a wider range of I/O ports probed.
- We have significantly reduced the amount of time it takes to load
- the driver and at the same time doubled the number of I/O ports
- probed increasing the likelihood of finding an adapter.
- - We now support all ISA adapter models with a single driver instead
- of separate drivers for each model. The revision 2 driver supports
- the DataCommute/BRI, DataCommute/PRI and TeleCommute/BRI in any
- combination up to a maximum of four adapters per system.
- - On board PPP protocol support has been removed in favour of the
- sync-PPP support used in ISDN4Linux. This means more control of
- the protocol parameters, faster negotiation time and a more
- familiar interface.
-
-1.3 How do I setup my system with the correct software to use
- this driver release?
-
-Before you can compile, install and use the SpellCaster ISA ISDN driver, you
-must ensure that the following software is installed, configured and running:
-
- - Linux kernel 2.0.20 or later with the required init and ps
- versions. Please see your distribution vendor for the correct
- utility packages. The latest kernel is available from
- ftp://sunsite.unc.edu/pub/Linux/kernel/v2.0/
-
- - The latest modules package (modules-2.0.0.tar.gz) from
- ftp://sunsite.unc.edu/pub/Linux/kernel/modules-2.0.0.tar.gz
-
- - The ISDN4Linux tools available from
- ftp://ftp.franken.de/pub/isdn4linux/v2.0/isdn4k-utils-2.0.tar.gz
- This package may fail to compile for you so you can alternatively
- get a pre-compiled version from
- ftp://ftp.spellcast.com/pub/drivers/isdn4linux/isdn4k-bin-2.0.tar.gz
-
-
-2. Basic Operations
--------------------
-
-2.1 Unpacking and installing the driver
-
- 1. As root, create a directory in a convenient place. We suggest
- /usr/src/spellcaster.
-
- 2. Unpack the archive with :
- tar xzf sc-n.nn.tar.gz -C /usr/src/spellcaster
-
- 3. Change directory to /usr/src/spellcaster
-
- 4. Read the README and RELNOTES files.
-
- 5. Run 'make' and if all goes well, run 'make install'.
-
-2.2 Read the man pages!!!
-
-Make sure you read the scctrl(8) and sc(4) manual pages before continuing
-any further. Type 'man 8 scctrl' and 'man 4 sc'.
-
-2.3 Installing the driver
-
-To install the driver, type '/sbin/insmod sc' as root. sc(4) details options
-you can specify but you shouldn't need to use any unless this doesn't work.
-
-Make sure the driver loaded and detected all of the adapters by typing
-'dmesg'.
-
-The driver can be configured so that it is loaded upon startup. To do this,
-edit the file "/etc/modules/'uname -f'/'uname -v'" and insert the driver name
-"sc" into this file.
-
-2.4 Removing the driver
-
-To remove the driver, delete any interfaces that may exist (see isdnctrl(8)
-for more on this) and then type '/sbin/rmmod sc'.
-
-2.5 What to do if it doesn't load
-
-If, when you try to install the driver, you get a message mentioning
-'register_isdn' then you do not have the ISDN4Linux system installed. Please
-make sure that ISDN support is configured in the kernel.
-
-If you get a message that says 'initialization of sc failed', then the
-driver failed to detect an adapter or failed to find resources needed such
-as a free IRQ line or shared memory segment. If you are sure there are free
-resources available, use the insmod options detailed in sc(4) to override
-the probing function.
-
-Upon testing, the following problem was noted, the driver would load without
-problems, but the board would not respond beyond that point. When a check was
-done with 'cat /proc/interrupts' the interrupt count for sc was 0. In the event
-of this problem, change the BIOS settings so that the interrupts in question are
-reserved for ISA use only.
-
-
-2.6 How to setup ISDN4Linux with the driver
-
-There are three main configurations which you can use with the driver:
-
-A) Basic HDLC connection
-B) PPP connection
-C) MLPPP connection
-
-It should be mentioned here that you may also use a tty connection if you
-desire. The Documentation directory of the isdn4linux subsystem offers good
-documentation on this feature.
-
-A) 10 steps to the establishment of a basic HDLC connection
------------------------------------------------------------
-
-- please open the isdn-hdlc file in the examples directory and follow along...
-
- This file is a script used to configure a BRI ISDN TA to establish a
- basic HDLC connection between its two channels. Two network
- interfaces are created and two routes added between the channels.
-
- i) using the isdnctrl utility, add an interface with "addif" and
- name it "isdn0"
- ii) add the outgoing and inbound telephone numbers
- iii) set the Layer 2 protocol to hdlc
- iv) set the eaz of the interface to be the phone number of that
- specific channel
- v) to turn the callback features off, set the callback to "off" and
- the callback delay (cbdelay) to 0.
- vi) the hangup timeout can be set to a specified number of seconds
- vii) the hangup upon incoming call can be set on or off
- viii) use the ifconfig command to bring up the network interface with
- a specific IP address and point to point address
- ix) add a route to the IP address through the isdn0 interface
- x) a ping should result in the establishment of the connection
-
-
-B) Establishment of a PPP connection
-------------------------------------
-
-- please open the isdn-ppp file in the examples directory and follow along...
-
- This file is a script used to configure a BRI ISDN TA to establish a
- PPP connection between the two channels. The file is almost
- identical to the HDLC connection example except that the packet
- encapsulation type has to be set.
-
- use the same procedure as in the HDLC connection from steps i) to
- iii) then, after the Layer 2 protocol is set, set the encapsulation
- "encap" to syncppp. With this done, the rest of the steps, iv) to x)
- can be followed from above.
-
- Then, the ipppd (ippp daemon) must be setup:
-
- xi) use the ipppd function found in /sbin/ipppd to set the following:
- xii) take out (minus) VJ compression and bsd compression
- xiii) set the mru size to 2000
- xiv) link the two /dev interfaces to the daemon
-
-NOTE: A "*" in the inbound telephone number specifies that a call can be
-accepted on any number.
-
-C) Establishment of a MLPPP connection
---------------------------------------
-
-- please open the isdn-mppp file in the examples directory and follow along...
-
- This file is a script used to configure a BRI ISDN TA to accept a
- Multi Link PPP connection.
-
- i) using the isdnctrl utility, add an interface with "addif" and
- name it "ippp0"
- ii) add the inbound telephone number
- iii) set the Layer 2 protocol to hdlc and the Layer 3 protocol to
- trans (transparent)
- iv) set the packet encapsulation to syncppp
- v) set the eaz of the interface to be the phone number of that
- specific channel
- vi) to turn the callback features off, set the callback to "off" and
- the callback delay (cbdelay) to 0.
- vi) the hangup timeout can be set to a specified number of seconds
- vii) the hangup upon incoming call can be set on or off
- viii) add a slave interface and name it "ippp32" for example
- ix) set the similar parameters for the ippp32 interface
- x) use the ifconfig command to bring-up the ippp0 interface with a
- specific IP address and point to point address
- xi) add a route to the IP address through the ippp0 interface
- xii) use the ipppd function found in /sbin/ipppd to set the following:
- xiii) take out (minus) bsd compression
- xiv) set the mru size to 2000
- xv) add (+) the multi-link function "+mp"
- xvi) link the two /dev interfaces to the daemon
-
-NOTE: To use the MLPPP connection to dial OUT to a MLPPP connection, change
-the inbound telephone numbers to the outgoing telephone numbers of the MLPPP
-host.
-
-
-3. Beta Change Summaries and Miscellaneous Notes
-------------------------------------------------
-When using the "scctrl" utility to upload firmware revisions on the board,
-please note that the byte count displayed at the end of the operation may be
-different from the total number of bytes in the "dcbfwn.nn.sr" file. Please
-disregard the displayed byte count.
-
-It was noted that in Beta Release 1, the module would fail to load and result
-in a segmentation fault when 'insmod'ed. This problem was created when one of
-the isdn4linux parameters, (isdn_ctrl, data field) was filled in. In some
-cases, this data field was NULL, and was left unchecked, so when it was
-referenced... segv. The bug has been fixed around line 63-68 of event.c.

- Say Y here if you have an IBM Active 2000 ISDN card. In order to use
- this card, additional firmware is necessary, which has to be loaded
- into the card using a utility which is part of the latest

- This enables support for two kinds of ISDN-cards made by a German
- company called ICN. 2B is the standard version for a single ISDN
- line with two B-channels, 4B supports two ISDN lines. For running
- this card, additional firmware is necessary, which has to be
- downloaded into the card using a utility which is distributed
- separately. See <file:Documentation/isdn/README> and
- <file:Documentation/isdn/README.icn> for more
- information.

+1) Support dma-buf memory management.
+
+In order to zero-copy import camera images into the 3D or display
+pipelines, we need to export our buffers through dma-buf so that the
+vc4 driver can import them. This may involve bringing in the VCSM
+driver (which allows long-term management of regions of memory in the
+space that the VPU reserved and Linux otherwise doesn't have access
+to), or building some new protocol that allows VCSM-style management
+of Linux's CMA memory.
+
+2) Avoid extra copies for padding of images.
+
+We expose V4L2_PIX_FMT_* formats that have a specified stride/height
+padding in the V4L2 spec, but that padding doesn't match what the
+hardware can do. If we exposed the native padding requirements
+through the V4L2 "multiplanar" formats, the firmware would have one
+less copy it needed to do.
+
+3) Port to ARM64
+
+The bulk_receive() does some manual cache flushing that are 32-bit ARM
+only, which we should convert to proper cross-platform APIs.
+
+4) Convert to be a platform driver.
+
+Right now when the module probes, it tries to initialize VCHI and
+errors out if it wasn't ready yet. If bcm2835-v4l2 was built in, then
+VCHI generally isn't ready because it depends on both the firmware and
+mailbox drivers having already loaded.
+
+We should have VCHI create a platform device once it's initialized,
+and have this driver bind to it, so that we automatically load the
+v4l2 module after VCHI loads.
+
+5) Drop the gstreamer workaround.
+
+This was a temporary workaround for a bug that was fixed mid-2014, and
+we should remove it before stabilizing the driver.
