Subject: [PATCH v3 3/9] clk: qcom: apss-ipq6018: mark apcs_alias0_core_clk as critical
Date: Fri, 19 Aug 2022 00:06:22 +0200 [thread overview]
Message-ID: <20220818220628.339366-3-robimarko@gmail.com> (raw)
In-Reply-To: <20220818220628.339366-1-robimarko@gmail.com>
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")
