Subject: [PATCH] clk: qcom: apss-ipq6018: mark apcs_alias0_core_clk as critical
Git-commit: 86e78995c93ee182433f965babfccd48417d4dcf
Patch-mainline: v6.1-rc1
References: git-fixes
While fixing up the driver I noticed that my IPQ8074 board was hanging
after CPUFreq switched the frequency during boot, WDT would eventually
reset it.
So mark apcs_alias0_core_clk as critical since its the clock feeding the
CPU cluster and must never be disabled.
