Hi Oleksij,

Old imx6q machine code makes RGMII/RMII clock direction decision based on
configuration of "ptp" clock. "enet_out" is not used and make no real
sense, since we can't configure it as output or use it as clock
provider.

Instead of "enet_out" use "enet_clk_ref" which is actual selector to
choose between internal and external clock source:

FEC MAC <---------- enet_clk_ref <--------- SoC PLL
                          \
			  ^------<-> refclock PAD (bi directional)

Please also update fec binding, otherwise there will be dtbs check error.

Thanks,
