FTR, I discovered two more issues with clock drivers registering a
genpd OF provider from CLK_OF_DECLARE(), which is now too early:
  1. drivers/clk/mmp/clk-of-mmp2.c,
  2. drivers/clk/renesas/clk-mstp.c.

I have submitted a fix for the second driver: "[PATCH] clk: renesas:
mstp: Add genpd OF provider at postcore_initcall()"
https://lore.kernel.org/all/81ef5f8d5d31374b7852b05453c52d2f735062a2.1755073087.git.geert+renesas@glider.be

I don't have MMP2 hardware, I guess it needs a similar fix.

Gr{oetje,eeting}s,

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.
