Subject: [PATCH v2 09/15] drivers: clk: qcom: gcc-ipq806x: add unusued flag for critical clock
Date: Fri, 21 Jan 2022 00:20:22 +0100	[thread overview]
Message-ID: <20220120232028.6738-10-ansuelsmth@gmail.com> (raw)
In-Reply-To: <20220120232028.6738-1-ansuelsmth@gmail.com>

Some clocks are used by other devices present on the SoC. For example
the gsbi4_h_clk is used by RPM and is if disabled cause the RPM to
reject any regulator change command. These clock should never be
disabled.
