Convert old text based binding to json schema.
Changes during conversion:
Add a fallback for all compatibles as the IP core is compatible
with `syscon`.

I don't understand. The syscon was already there. You added different
fallback, so provide explanation why do you think they are compatible.

See other bindings for preferred syntax. There is never anyOf.

So that's just enum with previous group.

The old binding was misleading, `microchip,sam9x60-matrix` has a
compatible `atmel,at91sam9x5-matrix` and `atmel,at91sam9x5-matrix` has a
compatible `syscon`, which was missing in the old binding. I will add
this to the commit message.

Yes, I will change that.

Yes, as both boards have 2 compatibles one after another, I defined them
as two different groups to resolve dt_check warnings.

Will use `syscon@` instead of `matrix@` in next revision.

Yes, I will remove the other group and define both `microchip,sam9x60-matrix` and `microchip,sam9x7-matrix` in enum under items and add const. > > > Best regards, > Krzysztof -- Best Regards, Charan.
