[PATCH v4 16/16] dt-bindings: clock: fix some conversion clock issues for rockchip,rk3399-cru.yaml

From: Johan Jonker
Date: Sat Apr 02 2022 - 10:37:50 EST


With the YAML conversion somehow "assigned-xxx" properties where added.
If a proper clock is added to the cru node these properties are no longer
needed, so removed them.

With the conversion of rockchip,rk3399-cru.txt a table with external clocks
was copied. Include these clocks into the schema.

Add clocks and clocks-names to example and make them a requirement.
Reorder/restyle so that this file is line with the other Rockchip
CRU bindings.

There are several clocks that are generated outside the SoC. It is expected

- - "xin32k" - rtc clock - optional,

- - "clk_usbphy1_480m" - output clock of the pll in the usbphy1
