Perhaps that should be done in a separate patch I feel. Will do so after this is
merged.

I would do it in the same patch, just like you remove some of the
.init_late() callbacks elsewhere, but it clearly works either way, so
do as you like unless Shawn or Sascha have a strong opinion on the
matter.

I think an #ifdef CONFIG_ARCH_RENESAS block wouldn't hurt, likewise

Soon you'll have this file filled with lots of compatible values for random\

This is going to be done once per boot and this shouldn't hurt. And for new
platforms we may do things differently as they are going to use opp-v2 bindings.
And, so I am not really in favor of ifdef hackery :)

I was mainly thinking about kernel size.
If this is done once per boot, the array should be __initconst,
(looking at the code
in next) which is fine as cpufreq_dt_platdev_init() is already __init.
Thanks!

Sure, makes sense.. I will do that as a separate patch.
Though just to correct what I earlier said, if cpufreq-dt is developed as a
module, its done once per module insertion :)

Have tested this patch on Hikey, it works well with new driver
cpufreq-dt-platdev.c.
