pgprot_dmachoerent() is not defined on every architecture. Having
COMPILE_TEST set for the driver causes it to be compiled on
architectures which do not have pgprot_dmachoerent():
drivers/misc/aspeed-lpc-ctrl.c: In function 'aspeed_lpc_ctrl_mmap':
drivers/misc/aspeed-lpc-ctrl.c:51:9: error: implicit declaration of
function 'pgprot_dmacoherent' [-Werror=implicit-function-declaration]
prot = pgprot_dmacoherent(prot);
There are two possible solutions:
1. Remove COMPILE_TEST to ensure the driver is only compiled on ARM
2. Use pgprot_noncached() instead of pgprot_dmachoerent()
The first option results in less compile testing of the LPC control
driver which is undesirable.
The second option uses a function that is declared on all architectures
and therefore should always build. Currently there is no practical
difference between pgprot_noncached() and pgprot_dmachoerent() for the
aspeed chips that this driver is compatible with. The reason for
pgprot_dmachoerent() was that there may be chips made at some point in
the future that could include hardware that pgprot_dmachoerent() could
optimise for. As none of this hardware has even been announced there
isn't really a need for pgprot_dmachoerent().
Using pgprot_noncached() is completely correct and optimal for all
existing hardware on which the LPC control driver will run.
This commit also addresses that phys_addr_t should be printed using %pap

This driver did not set kobj.parent so it likely suffered from
a potential use after free race if the user unregistered the
device while it was in use.
This was not so straightforward a conversion but I think this patch
cleans up its probe's error path significantly.
This patch adds device_initialize, which is required for
cdev_device_add. Then it switches to put_device instead of kfree as
recommended by device_initialize's documentation. This removes a lot
from the error path which was already in __remove.
A couple things needed to be re-ordered to be entirely correct, though.
ida_remove is also moved out of __remove and into unregister to
simplify things and follow the pattern other devices are using.
This also drop an extra unnecessary get_device/put_device in the code.

Mostly straightforward, but we had to remove the rtc_dev_add/del_device
functions as they split up the cdev_add and the device_add.
Doing this also revealed that there was likely another subtle bug:
seeing cdev_add was done after device_register, the cdev probably
was not ready before device_add when the uevent occurs. This would
race with userspace, if it tried to use the device directly after
the uevent. This is fixed just by using the new helper function.
Another weird thing is this driver would, in some error cases, call
cdev_add() without calling cdev_init. This patchset corrects this
by avoiding calling cdev_add if the devt is not set.

This driver did not originally set kobj.parent so it likely had
potential a use after free bug which this patch fixes.
We convert from device_register to device_initialize/cdev_device_add.
While we are at it we use put_device instead of kfree (as recommended
by the device_initialize documentation). We also remove an unnecessary
extra get_device from the code.

This is not as straightforward a conversion as the others
in this series. These drivers did not originally make use of
kobj.parent so they likely suffered from a use after free bug if
someone unregistered the devices while they are being used.
In order to make the conversions, switch from device_register
to device_initialize / cdev_device_add.
In build.c, this patch unwinds a complicated mess of extra
get_device/put_devices and reference tracking by moving device_initialize
early in the attach process. Then it always uses put_device and instead of
using device_unregister and extra get_devices everywhere we just use
cdev_device_del and one put_device once everything is completely done.
This simplifies things dramatically and makes it easier to reason about.
In vmt.c, the patch pushes device initialization up to the beginning of the
device creation and then that function only needs to use put_device
in the error path which simplifies things a good deal.

The use after free is not triggerable here because the cdev holds
the module lock and the only device_unregister is only triggered by
module unload, however make the change for consistency.
To make this work the cdev_del needs to move out of the struct device
release function.
This cleans up the error path significantly and thus also fixes a minor
bug where the devnum would not be released if cdev_add failed.

If device_add() fails, cleanup the cdev. Otherwise, we leak a kobj_map()

As Jason points out, there is a small possibility that userspace has
opened and mapped the device in the time between cdev_add() and the
device_add() failure. We need a new kill_dax_dev() helper to invalidate
any established mappings.

In 4-bit mode, 8-bit commands and data are written using two raw writes
to the data interface: high nibble first, low nibble last. This must be
handled by the low-level driver.
However, as we don't know in which mode (4-bit or 8-bit) nor 4-bit phase
the LCD was left, initialization must always be handled using raw
writes, and needs to configure the LCD for 8-bit mode first.

Extract the character LCD core from the Parallel port LCD/Keypad Panel
driver in the misc subsystem, and convert it into a subdriver in the
auxdisplay subsystem. This allows the character LCD core to be used by
other drivers later.
Compilation is controlled by its own Kconfig symbol CHARLCD, which is to
be selected by its users, but can be enabled manually for
compile-testing.
All functions changed their prefix from "lcd_" to "charlcd_", and gained
a "struct charlcd *" parameter to operate on a specific instance.
While the driver API thus is ready to support multiple instances, the
current limitation of a single display (/dev/lcd has a single misc minor
assigned) is retained.
No functional changes intended.

In order to manage server systems, there is typically another processor
known as a BMC (Baseboard Management Controller) which is responsible
for powering the server and other various elements, sometimes fans,
often the system flash.
The Aspeed BMC family which is what is used on OpenPOWER machines and a
number of x86 as well is typically connected to the host via an LPC
(Low Pin Count) bus (among others).
The LPC bus is an ISA bus on steroids. It's generally used by the
BMC chip to provide the host with access to the system flash (via MEM/FW
cycles) that contains the BIOS or other host firmware along with a
number of SuperIO-style IOs (via IO space) such as UARTs, IPMI
controllers.
On the BMC chip side, this is all configured via a bunch of registers
whose content is related to a given policy of what devices are exposed
at a per system level, which is system/vendor specific, so we don't want
to bolt that into the BMC kernel. This started with a need to provide
something nicer than /dev/mem for user space to configure these things.
One important aspect of the configuration is how the MEM/FW space is
exposed to the host (ie, the x86 or POWER). Some registers in that
bridge can define a window remapping all or portion of the LPC MEM/FW
space to a portion of the BMC internal bus, with no specific limits
imposed in HW.
I think it makes sense to ensure that this window is configured by a
kernel driver that can apply some serious sanity checks on what it is
configured to map.
In practice, user space wants to control this by flipping the mapping
between essentially two types of portions of the BMC address space:
- The flash space. This is a region of the BMC MMIO space that
more/less directly maps the system flash (at least for reads, writes
are somewhat more complicated).
- One (or more) reserved area(s) of the BMC physical memory.
The latter is needed for a number of things, such as avoiding letting
the host manipulate the innards of the BMC flash controller via some
evil backdoor, we want to do flash updates by routing the window to a
portion of memory (under control of a mailbox protocol via some
separate set of registers) which the host can use to write new data in
bulk and then request the BMC to flash it. There are other uses, such
as allowing the host to boot from an in-memory flash image rather than
the one in flash (very handy for continuous integration and test, the
BMC can just download new images).
It is important to note that due to the way the Aspeed chip lets the
kernel configure the mapping between host LPC addresses and BMC ram
addresses the offset within the window must be a multiple of size.
Not doing so will fragment the accessible space rather than simply
moving 'zero' upwards. This is caused by the nature of HICR8 being a
mask and the way host LPC addresses are translated.

Pull tty/serial fixes frpm Greg KH:
"Here are two bugfixes for tty stuff for 4.11-rc2.
One of them resolves the pretty bad bug in the n_hdlc code that

other just fixes a samsung serial driver issue when DMA fails on some
systems.
Both have been in linux-next with no reported issues"
