Jingoo Han e21d2170f3 video: remove unnecessary platform_set_drvdata()
The driver core clears the driver data to NULL after device_release
or on probe failure, since commit 0998d06310
(device-core: Ensure drvdata = NULL when no driver is bound).
Thus, it is not needed to manually clear the device driver data to NULL.

Lisa Du 3c76f15fd5 video: mmp: add tpo hvga panel supported
Add tpo hvga panel support in marvell display framework.  This panel
driver implements modes query and power on/off.

This panel driver gets panel config/ plat power on/off/ connected path
name from machine-info and registered as a spi device.  This panel
driver uses mmp_disp supplied register_panel function to register panel
to path as machine-info defined.

Arnd Bergmann 24cb87a761 fb: mmp: include linux/platform_device.h
Commit 16559ae48c ("kgdb: remove #include <linux/serial_8250.h> from
kgdb.h") changes the kgdb.h file so that drivers including it do not
implicitly include linux/platform_device.h.  The mmp framebuffer driver
is new, so Greg did not have a chance to fix it up when introducing his
change.

Zhou Zhu d2e8bae6d7 video: mmp fb support
Add fb support for Marvell mmp display subsystem.  This driver is
configured using "buffer driver mach info".  With configured name of path,
this driver get path using using exported interface of mmp display driver.
Then this driver get overlay using configured id and operates on this
overlay to show buffers on display devices.

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.
