- We tried via devicetree with the "qca,clk-out-frequency" property,
but it did not work. This is an area where you could add some debug prints inside drivers/net/phy/atheros.c and see if if qca,clk-out-frequency is being parsed correctly to configure a 125MHz clock output. This is the method I used on mx6cuboxi last week and it works.
To help debugging why "qca,clk-out-frequency" is not taking effect you could try this debug patch: https://pastebin.com/raw/RKG63JGJ
This is the result on a imx6 hummingboard: ....
