The pinctrl contexts for j722s should be saved and restored during
suspend-to-ram, just like it is done for j7200 and j784s4 SoCs.
Use ti,j7200-padconf compatible to save and restore pinctrl contexts during
suspend-to-ram.

It should be done at SoC level, not just for the EVM board.
You should modify k3-j722s-main.dtsi and create k3-j722s-mcu.dtsi.
Best Regards,
