But a system can have multiple mux-controllers which would require us to use mux-controller@0, mux-controller@1,.. And IIRC if we have "@", 'reg' will be a required required property. Would it be an issue here? Thanks Kishon

It's optional as getting folks to use 'reg' for syscon child nodes is an uphill battle.

The ti,j721e-system-controller binding does not follow the standard mux controller node name 'mux-controller' and the example is incomplete. Fix these to avoid schema errors before the mux controller binding is converted to schema.
