Hi Andy,

Yes, I agree. But how does a board designer practically describe this in the devicetree?
Example: mac_gtx -> clk_pad (the default)
Imagine I have a fixed oscillator on the board:
phy_ref_clk: oscillator { compatible = "fixed-clock"; #clock-cells = <0>; clock-frequency = <50000000>; };
How can I now make <&phy_ref_clk> the parent of <&clks CLK_PAD> ?
