Hi Simon,

   This patch is based on renesas-devel-20170622-v4.12-rc6 tag.
   It is verified on both H3 ES1.1 and ES2.0 SoC revisions.

   The bindings[1] and the driver[2] were pushed into the media_tree.

Thanks. Has this been tested not to cause regressions when
applied on top of renesas-devel-20170622-v4.12-rc6 (without the driver
changes) ?

Yes, I just tested it without the driver changes on top of renesas-devel-20170622-v4.12-rc6 and it works fine on both ES1.1 & 2.0s.

Thanks for the reminder and sorry for letting this slip through.
I have queued this up for v4.14.
