Patches 1 & 2 applied to the pin control tree for v6.19!

>   arm64: dts: cix: Add pinctrl nodes for sky1

This third patch should be applied to the SoC tree, Peter Chen or
Fugang Duan takes care of that I think? Not sure.

Good work with the pin controller, now is a good time to just
go on from here and fix the GPIO controllers using the pin
controller as back-end too :)

Yours,
Linus Walleij

Thanks, Linus.
Yes, since you have applied driver and dt-binding patches, I will
apply Dts patch to CIX SoC Tree.
