Subject: [PATCH 4/4] clk: qcom: mmcc-msm8998: Fix the SMMU GDSC
Date: Wed, 31 May 2023 11:01:23 +0200 [thread overview]
Message-ID: <20230531-topic-8998_mmssclk-v1-4-2b5a8fc90991@linaro.org> (raw)
In-Reply-To: <20230531-topic-8998_mmssclk-v1-0-2b5a8fc90991@linaro.org>
The SMMU GDSC doesn't have to be ALWAYS-ON and shouldn't feature the
HW_CTRL flag (it's separate from hw_ctrl_addr). In addition to that,
it should feature a cxc entry for bimc_smmu_axi_clk and be marked as
votable.
Fix all of these issues.
Fixes: d14b15b5931c ("clk: qcom: Add MSM8998 Multimedia Clock Controller (MMCC) driver")
