Notes:
checkpatch warns about un-documented binding
According to checkpatch the binding for "winbond,w25q128"
used in this dtsi is un-documented.
However, 'jedec,spi-nor.yaml' defines the pattern
(winbond,)?w25q(16|32(w|dw)?|64(dw)?|80bl|128(fw)?|256))$"
so, this should be good!?
Changes since v6:
- rename mdio0->mdio
Changes since v5:
- cleanup dt_bindings_check warnings
Changes since v4:
- cleanup usage of "status = okay|disabled"
- fix remaining non-generic node names
- rework sai nodes to not duplicate the existing settings in stm32mp151.dtsi
Changes since v3:
- cleanup board-compatible
- cleanup aliases
- rename nodes according to schema
- use interrupt flag
