Subject: [PATCH 4/8] clk: qcom: Add A7 PLL support for SDX65
Date:   Mon, 14 Feb 2022 12:29:47 +0530
Message-Id: <1644821987-27343-1-git-send-email-quic_rohiagar@quicinc.com>
Precedence: bulk

Add support for PLL found in Qualcomm SDX65 platforms which is used to
provide clock to the Cortex A7 CPU via a mux. This PLL can provide high
frequency clock to the CPU above 1GHz as compared to the other sources
like GPLL0.

In this driver, the power domain is attached to the cpudev. This is
required for CPUFreq functionality and there seems to be no better place
to do other than this driver (no dedicated CPUFreq driver).
