Merge branch 'add-property-in-dwmac-stm32-documentation'
Christophe Roullier says:
====================
Add property in dwmac-stm32 documentation
Introduce property in dwmac-stm32 documentation
- st,ext-phyclk: is present since 2020 in driver so need to explain
it and avoid dtbs check issue : views/kernel/upstream/net-next/arch/arm/boot/dts/st/stm32mp157c-dk2.dtb:
ethernet@5800a000: Unevaluated properties are not allowed
('st,ext-phyclk' was unexpected)
Furthermore this property will be use in upstream of MP13 dwmac glue. (next step)
====================
