[PATCH] dt-bindings: display: renesas: du: document R8A77980 bindings

[PATCH] dt-bindings: display: renesas: du: document R8A77980 bindings

[Sergei Shtylyov]

Document the R-Car V3H (R8A77980) SoC in the R-Car DU bindings; the DU
hardware seems the same as in the R-Car V3M (R8A77970).

Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

The patch is against the 'drm-next' branch of David Airlie's 'linux.git' repo.

Hi Sergei,

Thank you for the patch.

How about "the DU hardware has the same topology as in the R-Car V3M 
(R8A77970)" ? "seems" sounds like we're very unsure :-)

Then you might want to switch to git://anongit.freedesktop.org/drm/drm :-)

If you agree with the small change to the commit message I'll fix the conflict 
locally, there's no need to resubmit.

   That's probably better, indeed.

   No, the corresponding MAINTAINERS records don't include drivers/gpu/drm/rcar-du/
or worse yet, the DU bindings. :-)
  Seriously, I thought you've done a patch to remove your dead 'fbdev' repo months
ago and IO'm still seeing it listed... :-/

   I do agree, except I don't know what conflict you mean.

My point is that Dave's tree has moved.

   Well, there is still no corresponding record, actually...

   How am I supposed to learn about it, from gossips? :-)

I learnt it the hard way when a pull request I had prepared against the old 
tree conflicted (at compile time) with patches merged in the new tree. This 
broke the build, and I learnt about the new tree from a kbuild bot report.
