Thanks for the patches!

Andrew's patches [0] remove "syscon", "simple-mfd" from all the below
files except for k3-am62-wakeup.dtsi. But I think k3-am62-wakeup.dtsi
can be fixed up in the similar way and not really need a custom
system-controller binding. Last user is "ti-cpufreq" driver which is
being adapted over to use granular syscon nodes [1].

I believe add new compatible for system-controllers nodes is unneeded?

AM62 may need one more merge window to be resolved owing to dependencies
but I am queuing [0] to get rid of the warning for rest of the dts.

Bryan,

Could you repsin [1] with cleanups to am62-wakeup.dtsi as well?
