420a488278 video: fbdev: pxafb: initial devicetree conversion
This patch brings a first support of pxa framebuffer devices to a
devicetree pxa platform, as was before platform data.

There are restrictions with this port, the biggest one being the lack of
support of smart panels. Moreover the conversion doesn't provide a way
to declare multiple framebuffer configurations with different bits per
pixel, only the LCD hardware bus width is used.

The patch was tested on both pxa25x, pxa27x and pxa3xx platform (namely
lubbock, mainstone and zylonite).

5ec9653806 fbdev: Make fb-notify a no-op if CONFIG_FB=n
There's no point in having support for framebuffer notifications
is CONFIG_FB is disabled. This commit adds the necessary stubs
for code to link properly when CONFIG_FB=n and moves fb-notify.o
to be built only when CONFIG_FB=y.

5b833fea43 fbdev: sis: enforce selection of at least one backend
The sis framebuffer driver complains with a compile-time warning
if neither the FB_SIS_300 nor FB_SIS_315 symbols are selected:

drivers/video/fbdev/sis/sis_main.c:61:2: warning: #warning Neither CONFIG_FB_SIS_300 nor CONFIG_FB_SIS_315 is se

This is reasonable because it doesn't work in that case, but it's
also annoying for randconfig builds and is one of the most common
warnings I'm seeing on ARM now.

This changes the Kconfig logic to prevent the silly configuration,
by always selecting the FB_SIS_300 variant if the other one is
not set.

34280340b1 fbdev: Remove unused SH-Mobile HDMI driver
As of commit 44d88c754e ("ARM: shmobile: Remove legacy SoC code
for R-Mobile A1"), the SH-Mobile HDMI driver is no longer used.
In theory it could still be used on R-Mobile A1 SoCs, but that requires
adding DT support to the driver, which is not planned.

Remove the driver, it can be resurrected from git history when needed.

 Lots of things all over the place, almost all of them trivial fixups and
 changes.  The usual IIO updates and new drivers and we have added the
 MOST driver subsystem which is getting cleaned up in the tree.  The
 ozwpan driver is finally being deleted as it is obviously abandoned and
 no one cares about it.
 
 Full details are in the shortlog, and all of these have been in

71540cfbe9 fbdev: Allow compile test of GPIO consumers if !GPIOLIB
The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is
not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer
functionality only, can still be compiled if GPIOLIB is not enabled.

Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where
appropriate.

Device driver should not directly select subsystems. In this case

which we can avoid using the normal 'depends on' statement.

Also, this patch makes it possible for DRM drivers to have a dependency
on GPIOLIB without getting circular Kconfig dependencies.

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.

c0ee755fc5 Merge tag 'topic/core-stuff-2014-08-15' of git://anongit.freedesktop.org/drm-intel into drm-next
So small drm stuff all over for 3.18. Biggest one is the cmdline parsing
from Chris with a few fixes from me to make it work for stupid kernel
configs.

Plus the atomic prep series.

Tested for more than a week in -nightly and Ville/Imre indeed discovered
some fun which is now fixed (and i915 vblank patches postponed since the
fixups need this branch plus drm-intel-next merged together).

* tag 'topic/core-stuff-2014-08-15' of git://anongit.freedesktop.org/drm-intel:
  drm: Use the type of the array element when reallocating
  drm: Don't return 0 for a value used as a denominator
  drm: Docbook fixes
  drm/irq: Implement a generic vblank_wait function
  drm: Add a plane->reset hook
  drm: trylock modest locking for fbdev panics
  drm: Move ->old_fb from crtc to plane
  drm: Handle legacy per-crtc locking with full acquire ctx
  drm: Move modeset_lock_all helpers to drm_modeset_lock.[hc]
  drm: Add drm_plane/connector_index
  drm: idiot-proof vblank
  drm: Warn when leaking flip events on close
  drm: Perform cmdline mode parsing during connector initialisation
  video/fbdev: Always built-in video= cmdline parsing

ea6763c104 video/fbdev: Always built-in video= cmdline parsing
In drm/i915 we want to get at the video= cmdline modes even when we
don't have fbdev support enabled, so that users can always override
the kernel's initial mode selection.

But that gives us a direct depency upon the parsing code in the fbdev
subsystem. Since it's so little code just extract these 2 functions
and always build them in.

Whiel at it fix the checkpatch fail in this code.

v2: Also move fb_mode_option. Spotted by the kbuild.

v3: Review from Geert:
- Keep the old copyright notice from fb_mem.c, although I have no
idea what exactly applies.
- Only compile this when needed.

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.

423431a3b5 video: sh_mobile_lcdcfb depends on meram
The sh_mobile_lcdcfb driver calls interfaces provided
by the corresponding "meram" helper. This fails if meram
is a module but lcdcfb is built-in.

To work around it, this uses special Kconfig magic to
only allow lcdcfb to be built if
a) both are modules,
b) meram is built-in, or
c) meram is disabled and the helpers stubbed out

Changing meram from 'y' to 'm' now forces clcd to
be a module as well, which seems to be the desired
behavior.
