This patch series aims to add support for Renesas RZ/G1H (r8a7742) SoC.

RZ/G1H SoC is similar to R-Car Gen2 H2 SoC.

This patch set is based on renesas-drivers/master-v5.7-rc1.

Thanks for your series!

Looks mostly OK to me.
The missing code part seems to be the introduction of the main
CONFIG_ARCH_R8A7742 symbol?

I assume you plan to submit the DTS for v5.8, too, so I'll have to be
careful and apply the binding definitions to a separate shared branch?

Thanks again!

Thank you for the review. After fixing patch 8/10 shall I just post a
v2 with a single patch or the entire series ?

I was planning to post them once these patches were reviewed, just
didn't wanted to flood with too many patches.

for enabling r8a7742 SoC in multi_v7_defconfig should this be only
sent out wen its accepted in shmobile_defconfig or can it be part of
same series as below ?

05ba50a4cf99 ARM: multi_v7_defconfig: Enable r8a7742 SoC
99b69d08729a ARM: shmobile: defconfig: Enable r8a7742 SoC
6b7bcd6635c7 ARM: debug-ll: Add support for r8a7742
1cf4e52e3a0e soc: renesas: Add Renesas R8A7742 config option

Yes I do plan to submit the DTS changes for v5.8.

A single v2 patch is fine.  The clock driver goes in through a different
tree anyway/

It can be part of the same series.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
