One more thing, the way you mixed series makes it very difficult to
apply. Instead of applying few independent series, I need to:
1. Apply, drop patches (or apply 1-by-1).
2. Re-order patches.
3. Apply remaining 1-by-1 on pinctrl.

Please organize your series per subsystem. SoC is a subsystem. pinctrl
is different.

Bindings always go first, I asked for it already. And here everything is
mixed.

Best regards,
