From 28aa450d38e521de45be951df052d2c49a17fae2 Mon Sep 17 00:00:00 2001 From: Ansuel Smith Date: Sat, 26 Feb 2022 14:52:28 +0100 Subject: [PATCH 08/14] clk: qcom: gcc-ipq806x: add unusued flag for critical clock 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.
