[PATCH 2/2] dt-bindings: net: phy: vsc8531: document 'vsc8531,clkout-freq-mhz' property

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



For VSC8351 and similar PHYs, a new property was added to generate a clock
signal on the CLKOUT pin.
This change documents the change in the device-tree bindings doc.
