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.
