Hi all,
This patch series adds initial support for the Renesas R-Car V4M
(R8A779G0) SoC and the Renesas Gray Hawk Single development board.
As both driver code and DTS have hard dependencies on DT binding
definitions, most patches in this series are supposed to go in through
the renesas-devel and/or renesas-clk trees, using a shared branch for DT
binding definitions, as usual. For the PM domain patches (03, 04, 09),
Ulf already offered to apply these to his pmdomain tree, and provide an
immutable "dt" branch, to be pulled in my renesas-devel tree.
Changes compared to v1[1]:
- Add Acked-by, Reviewed-by,
- Add vendor-prefix to DT binding definition header file names and
update include guards,
- Add "board" to compatible comment,
- Add missing CP core clock,
- Add SoC name to top-level comment.
For testing, this series can be found at

Thanks for your comments!
