Subject: [PATCH 1/4] clk: qcom: clk-alpha-pll: Add support for lucid ole pll ops
Date:   Tue, 9 May 2023 21:42:15 +0530
Message-ID: <20230509161218.11979-2-quic_jkona@quicinc.com>

From: Taniya Das <quic_tdas@quicinc.com>

Add support for lucid ole pll ops to configure and control the
lucid ole pll. The lucid ole pll has an additional test control
register which is required to be programmed, add support to
program the same.
