Subject: [PATCH v3 2/3] arm64: dts: qcom: Add MSM8996v3.0 DTSI file
Date: Tue, 8 Jun 2021 17:27:35 +0200 [thread overview]
Message-ID: <20210608152737.154218-2-konrad.dybcio@somainline.org> (raw)
In-Reply-To: <20210608152737.154218-1-konrad.dybcio@somainline.org>
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.
Signed-off-by: Konrad Dybcio <konrad.dybcio@somainline.org>

Changes since v2:
