From: Oleksij Rempel <o.rempel@xxxxxxxxxxxxxx> commit f420f47e56c67587d9bc8f94267327b6fb214c1d upstream. 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.
