[RFC PATCH 00/12] Tegra: Add DC one-shot support

This patch set adds the Tegra dc one-shot support. The patch set is
tested on Dalmore + Sharp lq101r1sx01.

Basically this patch set is just for RFC. Some DRM files are changes,
I guess maybe there are better solutions for that. Also, Thierry
mentioned that "te-polarity" can be designed as a GPIO since not
every display controller has a dedicate TE pin like Tegra. So I
will try to create v2 after some comments are received.

Please be noticed that the patch #12 is not part of the feature,
it's just used for testing.

Mark Zhang (12):
  drm: Add a new mode flag: DRM_MODE_FLAG_PREFER_ONE_SHOT
  drm: panel: Add one-shot flag to Sharp lq101r1sx01 driver
  drm: panel: Turn on TE(Tearing Effect) on Sharp lq101r1sx01
  drm: Add DRM mode flag TE polarity
  dt: panel: Add property "te-polarity"
  drm: panel: Parse "te-polarity" in Sharp lq101r1sx01 driver
  drm/tegra: Set NC(Non-contiguous) mode to dc for one-shot
  drm/panel: Add panel func: idle/busy
  drm: dsi: Add "enter idle" & "exit idle" dcs functions
  drm: panel: Add idle/busy in Sharp lq101r1sx01 driver
  drm/tegra: Suspend dc/dsi/panel in one-shot mode
  JUST FOR TEST: Add one-shot trigger to update display
