Subject[PATCH v1] clk: imx6ul: fix "failed to get parent" error
Date
On some configuration we may get following error:
[ 0.000000] imx:clk-gpr-mux: failed to get parent (-EINVAL)

This happens if selector is configured to not supported value. To avoid
this warnings add dummy parents for not supported values.

Fixes: 4e197ee880c2 ("clk: imx6ul: add ethernet refclock mux support")
