It does not look like you tested the bindings, at least after quick
look. Please run `make dt_binding_check` (see
Documentation/devicetree/bindings/writing-schema.rst for instructions).
Maybe you need to update your dtschema and yamllint.

Beside that:
1. no underscores in property names.
2. Don't use syscon as an excuse for laziness. PLL is a clock, not syscon.

Best regards,
