[PATCH v3 3/6] clk: qcom: gcc-msm8998: Don't check halt bit on some branch clks

From: Konrad Dybcio <hidden>
Date: 2023-08-09 19:21:27
Also in: linux-arm-msm, linux-clk, linux-devicetree, linux-iommu, lkml
Subsystem: arm/qualcomm mailing list, common clk framework, qualcomm clock drivers, the rest · Maintainers: Michael Turquette, Stephen Boyd, Bjorn Andersson, Linus Torvalds

Some branch clocks are governed externally and we're only supposed to
send a request concerning their shutdown, not actually ensure it happens.

Use the BRANCH_HALT_SKIP define to skip checking the halt bit.

Fixes: db2c7c0a04b1 ("clk: qcom: Add missing msm8998 gcc_bimc_gfx_clk")
Fixes: b5f5f525c547 ("clk: qcom: Add MSM8998 Global Clock Control (GCC) driver")
