Stephen Warren 26549c8d36 drivers/video: implement a simple framebuffer driver
A simple frame-buffer describes a raw memory region that may be rendered
to, with the assumption that the display hardware has already been set
up to scan out from that buffer.

This is useful in cases where a bootloader exists and has set up the
display hardware, but a Linux driver doesn't yet exist for the display
hardware.

Examples use-cases include:

* The built-in LCD panels on the Samsung ARM chromebook, and Tegra
  devices, and likely many other ARM or embedded systems.  These cannot
  yet be supported using a full graphics driver, since the panel control
  should be provided by the CDF (Common Display Framework), which has been
  stuck in design/review for quite some time.  One could support these
  panels using custom SoC-specific code, but there is a desire to use
  common infra-structure rather than having each SoC vendor invent their
  own code, hence the desire to wait for CDF.

* Hardware for which a full graphics driver is not yet available, and
  the path to obtain one upstream isn't yet clear.  For example, the
  Raspberry Pi.

* Any hardware in early stages of upstreaming, before a full graphics
  driver has been tackled.  This driver can provide a graphical boot
  console (even full X support) much earlier in the upstreaming process,
  thus making new SoC or board support more generally useful earlier.

Fabio Estevam d7321df327 video: mxsfb: Adapt to new videomode API
commit 6cd2c7db4 (videomode: videomode_from_timing work) changed the name of
the function from videomode_from_timing() to videomode_from_timings().

commit 32ed6ef1 (videomode: create enum for videomode's display flags) changed
the 'data_flags' field in videomode structure to 'flags'

Adapt to these changes in order to fix the following errors:

drivers/video/mxsfb.c:761:3: error: too many arguments to function 'videomode_from_timing'
drivers/video/mxsfb.c:761:7: error: void value not ignored as it ought to be
drivers/video/mxsfb.c:768:9: error: 'struct videomode' has no member named 'data_flags'
drivers/video/mxsfb.c:770:9: error: 'struct videomode' has no member named 'data_flags'

Also, select VIDEOMODE_HELPER instead of OF_VIDEOMODE, as this one is
deprecated.

Linus Torvalds 5647ac0ad4 Removal of GENERIC_GPIO for v3.10
GENERIC_GPIO now synonymous with GPIOLIB. There are no longer any valid
 cases for enableing GENERIC_GPIO without GPIOLIB, even though it is
 possible to do so which has been causing confusion and breakage. This
 branch does the work to completely eliminate GENERIC_GPIO.
 
 However, it is not trivial to just create a branch to remove it. Over
 the course of the v3.9 cycle more code referencing GENERIC_GPIO has been
 added to linux-next that conflicts with this branch. The following must
 be done to resolve the conflicts when merging this branch into mainline:
 
 * "git grep CONFIG_GENERIC_GPIO" should return 0 hits. Matches should be
   replaced with CONFIG_GPIOLIB
 * "git grep '\bGENERIC_GPIO\b'" should return 1 hit in the Chinese
   documentation.
 * Selectors of GENERIC_GPIO should be turned into selectors of GPIOLIB
 * definitions of the option in architecture Kconfig code should be deleted.
 
 Stephen has 3 merge fixup patches[1] that do the above. They are currently
 applicable on mainline as of May 2nd.

Tony Prisk 7ab0a48420 video: fb: vt8500: Convert framebuffer drivers to standardized binding
Now that a display timing binding is available, convert our almost identical
binding to use the standard binding.

This patch converts the vt8500 and wm8505 framebuffer drivers and
associated dts/dtsi files to use the standard binding as defined in
bindings/video/display-timing.txt.

There are two side-effects of making this conversion:

1) The fb node should now be in the board file, rather than the soc file as
the display-timing node is a child of the fb node.

2) We still require a bits per pixel property to initialize the framebuffer
for the different lcd panels. Rather than including this as part of the
display timing, it is moved into the framebuffer node.

I have also taken the opportunity to alphabetise the includes of each

Tomi Valkeinen a38884f681 videomode: simplify videomode Kconfig and Makefile
This patch simplifies videomode related Kconfig and Makefile. After this
patch, there's only one non-user selectable Kconfig option left,
VIDEOMODE_HELPERS. The reasons for the change:

* Videomode helper functions are not something that should be shown in
  the kernel configuration options. The related code should just be
  included if it's needed, i.e. selected by drivers using videomode.

* There's no need to have separate Kconfig options for videomode and
  display_timing. First of all, the amount of code for both is quite
  small. Second, videomode depends on display_timing, and display_timing
  in itself is not really useful, so both would be included in any case.

* CONFIG_VIDEOMODE is a bit vague name, and CONFIG_VIDEOMODE_HELPERS
  describes better what's included.

Zhou Zhu 59393bb94c video: mmp display subsystem
Add mmp display subsystem to support Marvell MMP display controllers.

This subsystem contains 4 parts:
--fb folder
--core.c
--hw folder
--panel folder

1. fb folder contains implementation of fb.  fb get path and overlay
   from common interface and operates on these structures.

2. core.c provides common interface for a hardware abstraction.  Major
   parts of this interface are:

   a) Path: path is a output device connected to a panel or HDMI TV.  Main
      operations of the path is set/get timing/output color.  fb operates
      output device through path structure.

   b) Ovly: Ovly is a buffer shown on the path.

      Ovly describes frame buffer and its source/destination size, offset,
      input color, buffer address, z-order, and so on.  Each fb device maps
      to one overlay.

3. hw folder contains implementation of hardware operations defined by
   core.c.  It registers paths for fb use.

4. panel folder contains implementation of panels.  It's connected to
   path.  Panel drivers would also regiester panels and linked to path
   when probe.

methods to the usual Linux place and dropping the Android early suspend

Steffen Trumtrar cc3f414cf2 video: add of helper for display timings/videomode
This adds support for reading display timings from DT into a struct
display_timings. The of_display_timing implementation supports multiple
subnodes. All children are read into an array, that can be queried.

If no native mode is specified, the first subnode will be used.

For cases where the graphics driver knows there can be only one
mode description or where the driver only supports one mode, a helper
function of_get_videomode is added, that gets a struct videomode from DT.

Steffen Trumtrar 8714c0cecf video: add display_timing and videomode
Add display_timing structure and the according helper functions. This allows
the description of a display via its supported timing parameters.

Also, add helper functions to convert from display timings to a generic videomode
structure.

The struct display_timing specifies all needed parameters to describe the signal
properties of a display in one mode. This includes
    - ranges for signals that may have min-, max- and typical values
    - single integers for signals that can be on, off or are ignored
    - booleans for signals that are either on or off

As a display may support multiple modes like this, a struct display_timings is
added, that holds all given struct display_timing pointers and declares the
native mode of the display.

Although a display may state that a signal can be in a range, it is driven with
fixed values that indicate a videomode. Therefore graphic drivers don't need all
the information of struct display_timing, but would generate a videomode from
the given set of supported signal timings and work with that.

The video subsystems all define their own structs that describe a mode and work
with that (e.g. fb_videomode or drm_display_mode). To slowly replace all those
various structures and allow code reuse across those subsystems, add struct
videomode as a generic description.

This patch only includes the most basic fields in struct videomode. All missing
fields that are needed to have a really generic video mode description can be
added at a later stage.

 Major thing here is that the Broadcom bcmring platform is removed. It's an
 SoC that's used on some stationary VoIP platforms, and is in desperate
 need of some cleanup. Broadcom came back and suggested that we just
 deprecate the platform for now, since they aren't going to spend the
 resources needed on cleaning it up, and there are no users of the platform
 directly from mainline.

Merge tag 'cleanup2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM soc cleanups, part 2 from Olof Johansson:
 "A shorter cleanup branch submitted separately due to dependencies with
  some of the previous topics.

  Major thing here is that the Broadcom bcmring platform is removed.
  It's an SoC that's used on some stationary VoIP platforms, and is in
  desperate need of some cleanup.  Broadcom came back and suggested that
  we just deprecate the platform for now, since they aren't going to
  spend the resources needed on cleaning it up, and there are no users
  of the platform directly from mainline."

Fix some conflicts due to BCM2835 getting added next to the removed
BCMRING, and removal of tegra files that had been converted to
devicetree.

 "which has three neat features:

     all depends on CONFIG_XEN which depends on CONFIG_PARAVIRT which by

     into "default m" which I am going to post after the cpufreq git

Anatolij Gustschin f413070e3f fbdev: da8xx: add support for SP10Q010 display
Add timing data for Hitachi SP10Q010 display and allow configuration
of the 4bpp palette. For 4bpp framebuffer enable reversed order of
pixels in a byte. This requires defining FB_CFB_REV_PIXELS_IN_BYTE
and additionally setting var.nonstd to the value FB_NONSTD_REV_PIX_IN_B.
Note that it is not enough to set da8xx_fb_var.nonstd to this value
statically, since FBIOPUT_VSCREENINFO ioctl might pass var struct with
.nonstd field set to zero or another value. Therefore this setting must
be adjusted in fb_check_var() according to the requested bpp value.

PV-on-HVM guests may want to use the xen keyboard/mouse frontend, but
they don't use the xen frame buffer frontend. For this case it doesn't
make much sense for INPUT_XEN_KBDDEV_FRONTEND to depend on
XEN_FBDEV_FRONTEND. The opposite direction always makes more sense, i.e.
if you're using xenfb, then you'll want xenkbd. Switch the dependencies.
