Subject: clk: qcom: cmnpll: Add IPQ5332 SoC support
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1dcbf4195a262d57f4da812248cdbbcdc81bf8d8;p=thirdparty%2Fkernel%2Flinux.git

clk: qcom: cmnpll: Add IPQ5332 SoC support

The CMN PLL in IPQ5332 SoC produces different output clocks when compared
to IPQ9574. While most clock outputs match IPQ9574, the ethernet PHY/switch
(50 Mhz) and PPE clocks (200 Mhz) in IPQ5332 are different.

Add IPQ5332-specific clock definitions and of_device_id entry.
