Subject: [PATCH] arm64: dts: qcom: sc8280xp: make dispcc cast minimal vote on MMCX
Date: Mon, 26 Feb 2024 23:11:23 +0200 [thread overview]
Message-ID: <20240226211123.4192907-1-dmitry.baryshkov@linaro.org> (raw)
Add required-opps property to the display clock controller. This makes
it cast minimal vote on the MMCX lane to prevents resets caused by the
DisplayPort / panel probing.
Fixes: 57d6ef683a15 ("arm64: dts: qcom: sc8280xp: Define some of the display blocks")
