The system controller node manages the CTRL_MMR0 region.
Add serdes_ln_ctrl node which is used for controlling the SERDES lane mux.

Does not look like you tested the DTS against bindings. Please run `make
dtbs_check` (see Documentation/devicetree/bindings/writing-schema.rst
for instructions).
Ohkay. The base seems to be from k3-j7200-main.dtsi which has the node
name as mux-controller@4080 without reg property. After comments in v2,
I used '-' instead of adding reg property to this node. Will change the
node name again and add the reg property to fix the warning that I see
now with dtbs_check.
Thanks!!
