2020-07-19media: i2c: Add RDACM20 driverJacopo Mondi5-0/+1247
The RDACM20 is a GMSL camera supporting 1280x800 resolution images developed by IMI based on an Omnivision 10635 sensor and a Maxim MAX9271 GMSL serializer. The GMSL link carries power, control (I2C) and video data over a single coax cable.

2020-07-19media: i2c: Add MAX9286 driverKieran Bingham3-0/+1334
The MAX9286 is a 4-channel GMSL deserializer with coax or STP input and CSI-2 output. The device supports multicamera streaming applications, and features the ability to synchronise the attached cameras. CSI-2 output can be configured with 1 to 4 lanes, and a control channel is supported over I2C, which implements an I2C mux to facilitate communications with connected cameras across the reverse control channel.

2020-06-23media: i2c: imx290: fix reset GPIO pin handlingAndrey Konovalov1-3/+4
According to https://www.kernel.org/doc/Documentation/gpio/consumer.txt, - all of the gpiod_set_value_xxx() functions operate with the *logical* value. So in imx290_power_on() the reset signal should be cleared (de-asserted) with gpiod_set_value_cansleep(imx290->rst_gpio, 0), and in imx290_power_off() the value of 1 must be used to apply/assert the reset to the sensor. In the device tree the reset pin is described as GPIO_ACTIVE_LOW, and gpiod_set_value_xxx() functions take this into account, - when devm_gpiod_get_optional() is called with GPIOD_ASIS, the GPIO is not initialized, and the direction must be set later; using a GPIO without setting its direction first is illegal and will result in undefined behavior. Fix this by using GPIOD_OUT_HIGH instead of GPIOD_ASIS (this asserts the reset signal to the sensor initially).

With the current driver 'media-ctl -p' issued right after the imx290 driver is loaded prints: pad0: Source [fmt:unknown/0x0] The format value of zero is due to the current_format field of the imx290 struct not being initialized yet. As imx290_entity_init_cfg() calls imx290_set_fmt(), the current_mode field is also initialized, so the line which set current_mode to a default value in driver's probe() function is no longer needed.

git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media Pull media updates from Mauro Carvalho Chehab: - Media documentation is now split into admin-guide, driver-api and userspace-api books (a longstanding request from Jon); - The media Kconfig was reorganized, in order to make easier to select drivers and their dependencies; - The testing drivers now has a separate directory; - added a new driver for Rockchip Video Decoder IP; - The atomisp staging driver was resurrected. It is meant to work with 4 generations of cameras on Atom-based laptops, tablets and cell phones. So, it seems worth investing time to cleanup this driver and making it in good shape. - Added some V4L2 core ancillary routines to help with h264 codecs; - Added an ov2740 image sensor driver; - The si2157 gained support for Analog TV, which, in turn, added support for some cx231xx and cx23885 boards to also support analog standards; - Added some V4L2 controls (V4L2_CID_CAMERA_ORIENTATION and V4L2_CID_CAMERA_SENSOR_ROTATION) to help identifying where the camera is located at the device; - VIDIOC_ENUM_FMT was extended to support MC-centric devices; - Lots of drivers improvements and cleanups. * tag 'media/v5.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (503 commits) media: Documentation: media: Refer to mbus format documentation from CSI-2 docs media: s5k5baf: Replace zero-length array with flexible-array media: i2c: imx219: Drop <linux/clk-provider.h> and <linux/clkdev.h> media: i2c: Add ov2740 image sensor driver media: ov8856: Implement sensor module revision identification media: ov8856: Add devicetree support media: dt-bindings: ov8856: Document YAML bindings media: dvb-usb: Add Cinergy S2 PCIe Dual Port support media: dvbdev: Fix tuner->demod media controller link media: dt-bindings: phy: phy-rockchip-dphy-rx0: move rockchip dphy rx0 bindings out of staging media: staging: dt-bindings: phy-rockchip-dphy-rx0: remove non-used reg property media: atomisp: unify the version for isp2401 a0 and b0 versions media: atomisp: update TODO with the current data media: atomisp: adjust some code at sh_css that could be broken media: atomisp: don't produce errs for ignored IRQs media: atomisp: print IRQ when debugging media: atomisp: isp_mmu: don't use kmem_cache media: atomisp: add a notice about possible leak resources media: atomisp: disable the dynamic and reserved pools media: atomisp: turn on camera before setting it ...

2020-05-25media: s5k5baf: Replace zero-length array with flexible-arrayGustavo A. R. Silva1-1/+1
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs. So, this work (flexible-array member conversions) will also help to get completely rid of those sorts of issues. This issue was found with the help of Coccinelle.

2020-03-12media: i2c: ov5695: Fix power on and off sequencesDongchun Zhu1-18/+31
From the measured hardware signal, OV5695 reset pin goes high for a short period of time during boot-up. From the sensor specification, the reset pin is active low and the DT binding defines the pin as active low, which means that the values set by the driver are inverted and thus the value requested in probe ends up high. Fix it by changing probe to request the reset GPIO initialized to high, which makes the initial state of the physical signal low. In addition, DOVDD rising must occur before DVDD rising from spec., but regulator_bulk_enable() API enables all the regulators asynchronously. Use an explicit loops of regulator_enable() instead. For power off sequence, it is required that DVDD falls first. Given the bulk API does not give any guarantee about the order of regulators, change the driver to use regulator_disable() instead. The sensor also requires a delay between reset high and first I2C transaction, which was assumed to be 8192 XVCLK cycles, but 1ms is recommended by the vendor. Fix this as well.

2020-03-12media: i2c: imx219: Fix power sequenceLad Prabhakar1-0/+17
When supporting Rpi Camera v2 Module on the RZ/G2E, found the driver had some issues with rcar mipi-csi driver. The sensor never entered into LP-11 state. The powerup sequence in the datasheet[1] shows the sensor entering into LP-11 in streaming mode, so to fix this issue transitions are performed from "streaming -> standby" in the probe() after power up. With this commit the sensor is able to enter LP-11 mode during power up, as expected by some CSI-2 controllers.

2020-03-12media: tvp5150: make debug output more readableMarco Felsch1-3/+6
The debug output for tvp5150_selmux() isn't really intuitive. Register values are printed decimal formatted and the input/output driver states are printed as enum. Even more the "normal" output enum mapps to zero so a active output will printing output=0 and a inactive output=1. Change this by brinting the register values hex formatted and the states as more readable string.

2020-03-12media: tvp5150: add support to limit sdtv standardsMarco Felsch1-2/+74
The tvp5150 accepts NTSC(M,J,4.43), PAL (B,D,G,H,I,M,N) and SECAM video data and is able to auto-detect the input signal. The auto-detection does not work if the connector does not receive an input signal and the tvp5150 might not be configured correctly. This misconfiguration leads into wrong decoded video streams if the tvp5150 gets powered on before the video signal is present. Limit the supported sdtv standards according to the actual selected connector to avoid a misconfiguration.
