These are the first series of a set of patches to update the MSM display
drivers to support newer MDP versions and display modes (while also providing
a base for future display development). The original source for these patches
is the Google Android kernel tree located here:
http://android.git.kernel.org/kernel/msm.git

Arve Hjønnevåg (1):
  [ARM] msm_fb: Fix framebuffer console

Dima Zavin (3):
  video: msmfb: Put the partial update magic value into the fix_screen
    struct.
  [ARM] msm: mdp: Add support for RGBX 8888 image format.
  [ARM] msm: mdp: Set the correct pack pattern for XRGB/ARGB

This can then be tested by userspace to see if the capability is supported.
Userspace cannot rely on that value being left in var_screen, since userspace
itself can change it.

Don't allow non panning updates to bypass the wait for the panel to turn on.

Arve,

	This patch did not have a SOB from you. Would you sign off on this patch?
