[PATCH v1 0/5] imx6qp QuadPlus: support improved enet clocking

[Sven Van Asbroeck]

On the imx6qp QuadPlus, the h/w designers have improved enet clocking.

This patchset extends the clock tree to reflect the situation on QuadPlus.

This allows board designers to choose the enet clocking method by making
simple clocktree changes in the devicetree.

Default setting: external routing of enet_ref from pad to pad.

Example, change the default to enet_ref @ 125MHz clock routed internally:

&fec {
	assigned-clocks = <&clks IMX6QDL_CLK_ENET_PTP>,
			  <&clks IMX6QDL_CLK_ENET_REF>;
	assigned-clock-parents = <&clks IMX6QDL_CLK_ENET_REF>;
	assigned-clock-rates = <0>, <125000000>;
};
