[PATCH 3/6] clk: qcom: gcc-sdm660: Add missing clocks and GDSCs

From: Konrad Dybcio <hidden>
Date: 2021-02-20 15:57:34
Also in: linux-arm-msm, linux-clk, lkml, phone-devel
Subsystem: arm/qualcomm mailing list, common clk framework, open firmware and flattened device tree bindings, qualcomm clock drivers, the rest · Maintainers: Stephen Boyd, Brian Masney, Jerome Brunet, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Bjorn Andersson, Linus Torvalds

Add missing clocks and GDSCs to make sure LPASS, UFS and
MSS can access their respective clock domains.

Fixes: f2a76a2955c0 ("clk: qcom: Add Global Clock controller (GCC) driver for SDM660")
Signed-off-by: Konrad Dybcio <redacted>
