Hi folks,

here is the first few patches to enhance the PL111 with the following
objectives:

- Consolidation - use the panel bridge, which I figured out after some
  tinkering (yes I will fix TVE200 too).
- Handle the PL110 variant
- Handle the power-on delay documented in both manuals
- Add callbacks to handle subvariants, and a scratch implementation
  of the Versatile extra register (no Nomadik yet).

Next steps will be (I guess)

- Make the driver also use the dumb VGA connector bridge for the platforms
  that simply connects the PL11x to a DAC to VGA
- Proper panel driver for the Versatile board
- Nomadik and its panel
- When things work, stepwise move the ARM platforms using this over to
  the DRM PL111 driver

Stuff that gets properly reviewed I can queue on drm-misc myself these days.

Linus Walleij (7):
  drm/pl111: Cleanup local header file
  drm/pl111: Add all registers to debugfs
  drm/pl111: Replace custom connector with panel bridge
  drm/pl111: Enable PL110 variant
  drm/pl111: Insert delay before powering up PL11x
  drm/pl111: Add optional variant display en/disable callbacks
  drm/pl111: Add handling of Versatile platforms
