This patch should also be split into three different patches:
- The one adding the nodes for the controller to the DTSI
- The one adding the pinctrl nodes
- The one enabling the controller on the board.

A newline here please.

You called the node ps20, you probably want to call it the same way

several muxing options (as it's probably the case).

A whitespace after the comma please.

Hmmm, no, no comments in the DTS.
Especially when it's that trivial to enable.
