Thanks for the update!

You forgot to refresh after moving ARCH_RENESAS in v5 of "riscv:
Kconfig.socs: Add ARCH_RENESAS kconfig option", and after relying on
ARCH_R9A07G043 in drivers/soc/renesas/Kconfig.

PM and GPIOLIB are auto-selected by ARCH_R9A07G043 (through ARCH_RZG2L)
resp. SOC_RENESAS, so they can be dropped.  But it's better to do this
after the release of v6.2-rc1, when all pieces have fallen together.

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.
