Subject: [PATCH v7 6/6] arm64: dts: qcom: sc7280: Add Reset support for gpu
Date: Wed, 5 Oct 2022 14:37:04 +0530 [thread overview]
Message-ID: <20221005143618.v7.6.I6a1fca5d53c886c05ea3e24cd4282d31c9c0cd0b@changeid> (raw)
In-Reply-To: <1664960824-20951-1-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.
