From a569b10bf74ff9d62d3deb98890ff4a4b75eb81a Mon Sep 17 00:00:00 2001 From: Konrad Dybcio Date: Tue, 8 Jun 2021 22:21:40 +0200 Subject: [PATCH] arm64: dts: qcom: Add MSM8996v3.0 DTSI file Add an overlay for MSM8996v3.0, which is a pre-final revision of the said SoC. It has some stark differences with regards to GPU, or more specifically its power delivery path. Oh, and of course a different msm-id.
