From f420f47e56c67587d9bc8f94267327b6fb214c1d Mon Sep 17 00:00:00 2001 From: Oleksij Rempel Date: Fri, 10 Mar 2023 17:45:23 +0100 Subject: [PATCH] clk: imx6ul: fix "failed to get parent" error 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.
