From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

commit d16d538ff49145b153976bd8e124116d369db266 upstream.

Add support for r8a7742. The Renesas RZ/G1H (R8A7742) PCIe controller
is identical to the R-Car Gen2 family.

Sure, we can apply this (I assume it is for 4.4)? But it will not
really add any support, it just documents the binding... so I assume
this should go into series with patches that actually change the dts
(and probably tweak the drivers)?

Best regards,

We have already backported PCIEC[1] to Linux-4.4.y-cip. Only dt binding patch was pending.

Aha. Sorry for the noise. I'll apply it if there are no other
comments.

I don't see any problems with this patch. I applied and pushed.

Hi Pavel, Nobuhiro,

Please ignore this patch for Linux-4.4.y-cip. I have send another patch fixing tab between commit and commit id
in the patch description.
