+Subject: [PATCH] dt-bindings: clock: qcom: Add CMN PLL clock controller for
+ IPQ SoC
+
+The CMN PLL controller provides clocks to networking hardware blocks
+and to GCC on Qualcomm IPQ9574 SoC. It receives input clock from the
+on-chip Wi-Fi, and produces output clocks at fixed rates. These output
+rates are predetermined, and are unrelated to the input clock rate.
+The primary purpose of CMN PLL is to supply clocks to the networking
+hardware such as PPE (packet process engine), PCS and the externally
+connected switch or PHY device. The CMN PLL block also outputs fixed
+rate clocks to GCC, such as 24 MHZ as XO clock and 32 KHZ as sleep
+clock supplied to GCC.

++description:
++  The CMN (or common) PLL clock controller expects a reference
++  input clock. This reference clock is from the on-board Wi-Fi.
++  The CMN PLL supplies a number of fixed rate output clocks to
++  the devices providing networking functions and to GCC. These
++  networking hardware include PPE (packet process engine), PCS
++  and the externally connected switch or PHY devices. The CMN
++  PLL block also outputs fixed rate clocks to GCC. The PLL's
++  primary function is to enable fixed rate output clocks for
++  networking hardware functions used with the IPQ SoC.

+Subject: [PATCH] dt-bindings: clock: qcom: Add CMN PLL support for IPQ5424 SoC
+
+The CMN PLL block in the IPQ5424 SoC takes 48 MHZ as the reference
+input clock. The output clocks are the same as IPQ9574 SoC, except
+for the clock rate of output clocks to PPE and NSS.
+
+Also, add the new header file to export the CMN PLL output clock
+specifiers for IPQ5424 SoC.
