Subject: [PATCH] clk: qcom: gcc-sm8450: set OPS_PARENT_ENABLE on
gcc_sdcc2_apps_clk_src
Similar to how it works on other SoCs, the top frequency of the SDHCI2
core clock is generated by a separate PLL (peculiar design choice) that
is not guaranteed to be enabled (why does the clock framework not handle
this by default?).
Add the CLK_OPS_PARENT_ENABLE flag to make sure we're not muxing the
RCG input to a dormant source.
Fixes: db0c944ee92b ("clk: qcom: Add clock driver for SM8450")
