[PATCH v6 0/3] drm/panel: simple: Add mode support to devicetree

[Douglas Anderson <dianders@chromium.org>]

I'm reviving Sean Paul's old patchset to get mode support in device
tree.  The cover letter for his v3 is at:
https://lists.freedesktop.org/archives/dri-devel/2018-February/165162.html

v6 of this patch is just a repost of the 3 DRM patches in v5 rebased
atop drm-misc.  A few notes:
- I've dropped the bindings patch.  Commit 821a1f7171ae ("dt-bindings:
  display: Convert common panel bindings to DT schema") has landed and
  Rob H said [1] that when that landed the bindings were implicitly
  supported.
- Since the bindings patch was dropped I am assuming that Heiko
  can just pick up the .dts patches from the v5 series.  I
  double-checked with him and he confirmed this is fine.  Thus I
  have left the device tree patches out of this version.

There were some coding style discussions on v5 of the path but it's
been agreed that we can land this series as-is and after it lands we
can address the minor style issues.
