commit 257462dbf3ed ("pwm-backlight: switch to gpiod interface")
introduced a regression leading to acquiring a bogus GPIO-0 when
configured from DT without an 'enable-gpios' property.
The driver will happily accept the 0 initialized 'enable_gpio' member
of the struct platform_pwm_backlight_data as valid gpio number, and
request this GPIO as enable pin. In case of multiple driver instances,
the second will fail to register with the error message:
pwm-backlight backlight1.23: failed to request GPIO#0: -16
Fix this by setting enable_gpio in the pdata struct to -EINVAL.

We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to
meet kernel coding style guidelines. This issue was reported by checkpatch.
A simplified version of the semantic patch that makes this change is as
follows (http://coccinelle.lip6.fr/):
// <smpl>
@@
identifier i;
declarer name DEFINE_PCI_DEVICE_TABLE;
initializer z;
@@
- DEFINE_PCI_DEVICE_TABLE(i)
+ const struct pci_device_id i[]
= z;

"A handful of driver-related changes. We've had a bunch of them going
in through other branches as well, so it's only a part of what we

Larger pieces are:

Pull ARM SoC cleanups from Olof Johansson:
"This merge window brings a good size of cleanups on various platforms.
Among the bigger ones:
- Removal of Samsung s5pc100 and s5p64xx platforms. Both of these
have lacked active support for quite a while, and after asking
around nobody showed interest in keeping them around. If needed,
they could be resurrected in the future but it's more likely that
we would prefer reintroduction of them as DT and
multiplatform-enabled platforms instead.
- OMAP4 controller code register define diet. They defined a lot of
registers that were never actually used, etc.
- Move of some of the Tegra platform code (PMC, APBIO, fuse,
powergate) to drivers/soc so it can be shared with 64-bit code.
This also converts them over to traditional driver models where
possible.
- Removal of legacy gpio-samsung driver, since the last users have
been removed (moved to pinctrl)

dissapear in the diffstat for the above. clps711x cleanups, shmobile
header file refactoring/moves for multiplatform friendliness, some

Currently the VSC has no chance to notify the VSP of the dirty rectangle on VM
panic because the notification work is done in a workqueue, and in panic() the
kernel typically ends up in an infinite loop, and a typical kernel config has
CONFIG_PREEMPT_VOLUNTARY=y and CONFIG_PREEMPT is not set, so a context switch
can't happen in panic() and the workqueue won't have a chance to run. As a
result, the VM Connection window can't refresh until it's closed and we
re-connect to the VM.
We can register a handler on panic_notifier_list: the handler can notify
the VSC and switch the framebuffer driver to a "synchronous mode", meaning
the VSC flushes any future framebuffer change to the VSP immediately.

The Versatile CLCD helpers call dma_alloc_writecombine() which is only
available on ARM and AVR32, meaning they won't build on other platforms
including arm64. Unfortunately the current Kconfig enables the symbol
by default if ARCH_VEXPRESS is defined which means that it is enabled on
arm64 when building for the ARM reference platforms and models for ARMv8
since they have many hardware similarities with their pre-ARMv8 systems.
Since all the systems that need the helpers are ARM systems fix this by
adding a dependency on ARM.

commit 11c32d7b6274cb0f ("video: move Versatile CLCD helpers")
moved files out of the plat-versatile directory but in the process
got a few of the dependencies wrong:
- If CONFIG_FB is not set, the file no longer gets built, resulting
in a link error
- If CONFIG_FB or CONFIG_FB_ARMCLCD are disabled, we also get a
Kconfig warning for incorrect dependencies due to the symbol
being 'select'ed from the platform Kconfig.
- When the file is not built, we also get a link error for missing
symbols.
This patch should fix all three, by removing the 'select' statements,
changing the Kconfig description of the symbol to be enabled in
exactly the right configurations, and adding inline stub functions
for the case when the framebuffer driver is disabled.

Commit b4aa0163056b ("efifb: Implement vga_default_device() (v2)") added
efifb vga_default_device() so EFI systems that do not load shadow VBIOS or
setup VGA get proper value for boot_vga PCI sysfs attribute on the
corresponding PCI device.
Xorg doesn't detect devices when boot_vga=0, e.g., on some EFI systems such
as MacBookAir2,1. Xorg detects the GPU and finds the DRI device but then
bails out with "no devices detected".
Note: When vga_default_device() is set boot_vga PCI sysfs attribute
reflects its state. When unset this attribute is 1 whenever
IORESOURCE_ROM_SHADOW flag is set.
With introduction of sysfb/simplefb/simpledrm efifb is getting obsolete
while having native drivers for the GPU also makes selecting sysfb/efifb
optional.
Remove the efifb implementation of vga_default_device() and initialize
vgaarb's vga_default_device() with the PCI GPU that matches boot
screen_info in pci_fixup_video().

The atmel-pwm-bl driver is now obsolete. It is not used by any mainlined boards
and is replaced by the generic pwm_bl with the pawm-atmel driver using the
generic PWM framework.

We no longer need the horrible driver internal videmode tables, which
were used to decide if a given videomode is a HDMI or DVI mode. So
remove all related code.

Instead of using hardcoded AVI infoframe, and a custom HDMI/DVI mode
selection based in internal videomode tables, add support to set the
infoframe and HDMI/DVI mode.

will be used in the following patches for OMAP4 and OMAP5 HDMI.

We now use the common AVI infoframe support, so the OMAP specific AVI
infoframe code can be removed.

OMAP HDMI driver has an 'enum hdmi_audio_sample_size', which conflicts
with the common include/linux/hdmi.h.
Change the name of the OMAP specific enum with '_omap" postfix.

dispc_mgr_timings_ok() is a bit confusing how it handles the return
value.
Change the function to just return immediately when a timing is deemed
not valid, making the code much easier to follow.

OMAP2/3 does not support interlace for LCD out. OMAP4+ does, but is not
supported by the driver at the moment.
The driver still accepts interlaced mode for LCD out, causing broken
display output.
This patch makes dispc reject interlace for LCD out.

The surrounding code and the fact that the previous two if's are
rendered useless without this "else" (since SIS_340==55 and XGI_20==75
are greater than SIS_661==15) suggests that the "else" is indeed
missing.
