a7f91edfdd OMAPDSS: DSI: Fix PLL_SELFEQDCO field width
PLL_SELFREQDCO bitfield is from bit 3 to 1, but the driver writes bits
from 4 to 1. The bit 4 is 'reserved', so this probably should not cause
any issues, but it's better to fix it.

0856eba75c OMAPDSS: HDMI: fix regsd write

88e3c76a8a OMAPDSS: HDMI: fix PLL GO bit handling
The PLL settings are committed by setting GO bit, which is then cleared
by the HW when the settings have been taken into use.

The current PLL code handles this wrong: instead of waiting for the bit
to be cleared, it waits for the bit to be set. Usually, the bit is
always set, as the CPU has just set it before. However, if the CPU takes
enough time between setting the GO bit and checking it, the HW may
already have cleared the bit and this leads to timeout error.

Fix the wait to check the bit properly.

13a0c40a49 OMAPFB: fix releasing overlays
omapfb disables all the overlays when freeing resources, but it should
also remove those overlays from overlay managers.

Not doing so causes a crash if omapfb is unbound and bound, or omapfb
module is removed and loaded, while keeping omapdss around.

Fix this by calling unset_manager() for all overlays.

63cec5a22c OMAPFB: fix overlay disable when freeing resources.
When omapfb is shutting down, it will disable all the overlays. However,
instead of actually disabling all the overlays, it disables only all the
overlays that are currently attached to framebuffers.

On OMAP4+, this leaves the fourth overlay left enabled.

Fix the loop so that we actually go through all the overlays.

37773c4e7f fbcon: Fix option parsing control flow in fb_console_setup
Since strsep is used to tokenize the options string, after each option
match the code should use "continue" to get the next token from strsep.
This patch applies this pattern consistently.

Previously, for "scrollback:" and "map:" the parse code would return
(unconditionally: strsep ensures *options != ','), causing any
following option to be ignored, while for "vc:" the parse code would
go on to parse further options within the same token, which could lead
to invalid input being accepted.

c4dd08694b video: fbdev: replace strnicmp with strncasecmp
The kernel used to contain two functions for length-delimited,
case-insensitive string comparison, strnicmp with correct semantics and
a slightly buggy strncasecmp.  The latter is the POSIX name, so strnicmp
was renamed to strncasecmp, and strnicmp made into a wrapper for the new
strncasecmp to avoid breaking existing users.

To allow the compat wrapper strnicmp to be removed at some point in the
future, and to avoid the extra indirection cost, do
s/strnicmp/strncasecmp/g.

ea584595fc This is the bulk of GPIO changes for the v3.18 development
cycle:
 
 - Increase the default ARCH_NR_GPIO from 256 to 512. This
   was done to avoid having a custom <asm/gpio.h> header for
   the x86 architecture - GPIO is custom and complicated
   enough as it is already! We want to move to a radix to
   store the descriptors going forward, and finally get rid
   of this fixed array size altogether.
 
 - Endgame patching of the gpio_remove() semantics initiated

a00d91ea26 fbdev: sh_mobile_hdmi: Re-init regs before irq re-enable on resume
When the PM domain containing the HDMI hardware block is powered down,
the HDMI register values (incl. interrupt polarity settings) are lost.
During resume, after powering up the PM domain, interrupts are
re-enabled, and an interrupt storm happens due to incorrect interrupt
polarity settings:

    irq 163: nobody cared (try booting with the "irqpoll" option)
    ...
    Disabling IRQ #163

To fix this, re-initialize the interrupt polarity settings, and the
htop1 register block (if present), during resume.

As the .suspend_noirq() and .resume_noirq() callbacks are not called
when using the generic PM domain, the normal .resume() callback is used,
and the device interrupt needs to be disabled/enabled manually.

This fixes resume from s2ram with power down of the A4MP PM domain on
r8a7740/Armadillo.

5b789da8a7 framebuffer: fix screen corruption when copying
The function bitcpy_rev has a bug that may result in screen corruption.
The bug happens under these conditions:
* the end of the destination area of a copy operation is aligned on a long
  word boundary
* the end of the source area is not aligned on a long word boundary
* we are copying more than one long word

In this case, the variable shift is non-zero and the variable first is
zero. The statements FB_WRITEL(comp(d0, FB_READL(dst), first), dst) reads
the last long word of the destination and writes it back unchanged
(because first is zero). Correctly, we should write the variable d0 to the
last word of the destination in this case.

This patch fixes the bug by introducing and extra test if first is zero.

The patch also removes the references to fb_memmove in the code that is
commented out because fb_memmove was removed from framebuffer subsystem.

f74a289b94 framebuffer: fix border color
The framebuffer code uses the current background color to fill the border
when switching consoles, however, this results in inconsistent behavior.
For example:
- start Midnigh Commander
- the border is black
- switch to another console and switch back
- the border is cyan
- type something into the command line in mc
- the border is cyan
- switch to another console and switch back
- the border is black
- press F9 to go to menu
- the border is black
- switch to another console and switch back
- the border is dark blue

When switching to a console with Midnight Commander, the border is random
color that was left selected by the slang subsystem.

This patch fixes this inconsistency by always using black as the
background color when switching consoles.

9c8ee3c734 video: mx3fb: always enable BACKLIGHT_LCD_SUPPORT
Commit 7edaa761ee ("video: mx3fb: Add backlight control support")
changed the mx3fb driver so it always selects the BACKLIGHT_CLASS_DEVICE
symbol, but that is hidden behind BACKLIGHT_LCD_SUPPORT in Kconfig, so
we get a Kconfig warning for multi_v5_defconfig, which doesn't have that:

Warning: (DRM_RADEON && DRM_NOUVEAU && DRM_I915 && DRM_GMA500 &&
DRM_SHMOBILE && DRM_TILCDC && FB_BACKLIGHT && FB_MX3 && USB_APPLEDISPLAY
&& FB_OLPC_DCON && ASUS_LAPTOP && SONY_LAPTOP && THINKPAD_ACPI &&
EEEPC_LAPTOP && ACPI_CMPC && SAMSUNG_Q10) selects BACKLIGHT_CLASS_DEVICE
which has unmet direct dependencies (HAS_IOMEM && BACKLIGHT_LCD_SUPPORT)

This makes sure we always enable both symbols together for mx3fb, like
we do for the other drivers that can't be built without backlight
support. Note that a better solution would be to ensure the driver can
work with or without backlight support.
