   4 Subject: clk: qcom: Move cxo/pxo/xo into dt files
   5
   6 Put these clocks into the dt files instead of registering them
   7 from C code. This provides a few benefits. It allows us to
   8 specify the frequency of these clocks at the board level instead
   9 of hard-coding them in the driver. It allows us to insert an RPM
  10 clock in between the consumers of the crystals and the actual
  11 clock. And finally, it helps us transition the GCC driver to use
  12 RPM clocks when that configuration is enabled.
