   4 Subject: [PATCH 08/14] clk: qcom: gcc-ipq806x: add unusued flag for critical
   5  clock
   6
   7 Some clocks are used by other devices present on the SoC. For example
   8 the gsbi4_h_clk is used by RPM and is if disabled cause the RPM to
   9 reject any regulator change command. These clock should never be
  10 disabled.
