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