Subject: [PATCH v3 3/6] clk: qcom: gcc-msm8998: Don't check halt bit on
some branch clks
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")
Reviewed-by: Jeffrey Hugo <quic_jhugo@...cinc.com>
