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> ?
