Subject: [PATCH 11/15] dt-bindings: display/msm: Document A845 GPU and GMU
Date: Wed, 23 Sep 2026 15:55:51 +0530 [thread overview]
Message-ID: <20260923-hawi-gpu-v1-11-0c3c79a1a470@oss.qualcomm.com> (raw)
In-Reply-To: <20260923-hawi-gpu-v1-0-0c3c79a1a470@oss.qualcomm.com>
From: Bhaskar Reddy Valluru <bvalluru@qti.qualcomm.com>
Adreno 845 GPU is present in the Maili SoC which is very similar to the
A850 GPU, except the MALU block. It has different set of power
configurations and the GMU clock list. Document this GPU and its GMU.
