    Subject[PATCH 6.0 568/862] clk: qcom: apss-ipq6018: mark apcs_alias0_core_clk as critical
    Date
    From: Robert Marko <robimarko@gmail.com>

    [ Upstream commit 86e78995c93ee182433f965babfccd48417d4dcf ]

    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.

    Fixes: 5e77b4ef1b19 ("clk: qcom: Add ipq6018 apss clock controller")
