4d4e2c003b video: da8xx-fb: preserve display width when changing HSYNC
When looking at this driver for a client, I noticed the code that
configures the HSYNC pulse clobbers the display width in the same
register.  It only preserves the MS part of the width in bit 3 and zeros
the LS part of the width in bits 9 to 4.  This doesn't matter during
initialization as the width is configured afterwards, but subsequent use
of the FBIPUT_HSYNC ioctl would clobber the width.

Preserve bits 9 to 0 of LCD_RASTER_TIMING_0_REG when configuring the
horizontal sync.

2b6c53b150 video: ARM CLCD: Fix calculation of bits-per-pixel
If the device-tree specifies a max-memory-bandwidth property then the
CLCD driver uses that to calculate the bits-per-pixel supported,
however, this calculation is faulty for two reasons.

1. It doesn't ensure that the result is a sane value, i.e. a power of 2
   and <= 32 as the rest of the code assumes.

2. It uses the displayed resolution and calculates the average bandwidth
   across the whole frame. It should instead calculate the peak
   bandwidth based on the pixel clock.

This patch fixes both the above.

754d561ab6 fbdev: Remove __init from chips_hw_init() to fix build failure
Fix build failure caused as follows:

The function chipsfb_pci_init() references
the function __init chips_hw_init().
This is often because chipsfb_pci_init lacks a __init
annotation or the annotation of chips_hw_init is wrong.

make: *** [drivers] Error 2

by removing the __init annotation from chips_hw_init(). The other thing that
could have been done was annotating chipsfb_pci_init(). But that cannot be done
since chipsfb_pci_init() is called from non __init functions.

937222c4dd pwm-backlight: Fix bogus request for GPIO#0 when instantiated from DT
commit 257462dbf3 ("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.

10c8e05620 ARM: SoC driver changes for 3.17
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 really have this release.
 
 Larger pieces are:
 
 * Removal of a now unused PWM driver for atmel
   - This includes AVR32 changes that have been appropriately acked.
 * Performance counter support for the arm CCN interconnect
 * OMAP mailbox driver cleanups and consolidation
 * PCI and SATA PHY drivers for SPEAr 13xx platforms
 * Redefinition (with backwards compatibility!) of PCI DT bindings for Tegra to
   better model regulators/power.

 * 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

3686fe9642 video: hyperv: hyperv_fb: refresh the VM screen by force on VM panic
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.

v2: removed the MS-TFS line in the commit message
v3: remove some 'unlikely' markings
v4: avoid global variables as Tomi Valkeinen suggested

94f30477fc video: clcd-versatile: Depend on ARM
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.

ec4c4d877b video: fix up versatile CLCD helper move
commit 11c32d7b62 ("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.

20cde69402 x86, ia64: Move EFI_FB vga_default_device() initialization to pci_vga_fixup()
Commit b4aa016305 ("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().
