Subject: [PATCH v2 5/5] arm64: dts: qcom: sc7280: Add Reset support for gpu
Date: Wed, 17 Aug 2022 20:27:54 +0530 [thread overview]
Message-ID: <20220817202609.v2.5.I6a1fca5d53c886c05ea3e24cd4282d31c9c0cd0b@changeid> (raw)
In-Reply-To: <1660748274-39239-1-git-send-email-quic_akhilpo@quicinc.com>
Add support for Reset using GPUCC driver for GPU. This helps to ensure
that GPU state is reset by making sure that CX head switch is collapsed.
