From 58c0b917fdca3a6052d61bd1df140ea6e8a22763 Mon Sep 17 00:00:00 2001 From: Konrad Dybcio Date: Mon, 29 Dec 2025 21:47:40 +0100 Subject: [PATCH] arm64: dts: qcom: agatti: Add CX_MEM/DBGC GPU regions [ Upstream commit 0fdcc948929a6d673bd0f90631dd6e42090c3dbd ] Describe the GPU register regions, with the former existing but not being used much if at all on this silicon, and the latter containing various debugging levers generally related to dumping the state of the IP upon a crash.
