   4 Subject: [PATCH 58/69] clk: qcom: Always add factor clock for xo clocks
   5
   6 Currently the RPM/RPM-SMD clock drivers do not register the xo clocks,
   7 so we should always add factor clock. When we later add xo clocks support
   8 into the drivers, we should update this function to skip registration.
   9 By doing so we avoid any DT dependencies.
