For the initial submission, it's better to use hardcoded numbers than the
R8A77965_CLK_* definitions, as the latter go in through a different tree.
Hence you should replace above include by

    #include <dt-bindings/clock/renesas-cpg-mssr.h>

and replace R8A77965_CLK_* by hardcoded numbers in all r8a77965.dtsi
patches.

For the initial submission, it's better to use hardcoded numbers than the
R8A77965_PD_* definitions, as the latter go in through a different tree.
Hence you should drop the above include, and replace R8A77965_PD_*
by hardcoded numbers in all r8a77965.dtsi patches.

The hardcoded numbers can be replaced by symbolic definitions later,
when the definitions have hit mainline.

Thanks!

Gr{oetje,eeting}s,

                        Geert

when I'm talking to journalists I just say "programmer" or something like that.
