Subject: [PATCH] clk: qcom: mmcc-msm8974: Fix mmss_s0_axi clock
Date: Sat, 26 Dec 2020 15:09:34 +0100	[thread overview]
Message-ID: <20201226140934.89856-1-konrad.dybcio@somainline.org> (raw)

On boards without cont_splash the clock wouldn't get enabled.
Reparent it and strongly depend on the parent to make sure
it's accessible. Access to MMSS depends on mmss_s0_axi being
up and alive.

Fixes: d8b212014e69 ("clk: qcom: Add support for MSM8974's multimedia clock controller (MMCC)")
