Subject: [PATCH v4 2/4] arm64: dts: qcom: Add MSM8996v3.0 DTSI file
Date: Tue,  8 Jun 2021 22:21:40 +0200	[thread overview]
Message-ID: <20210608202143.247427-2-konrad.dybcio@somainline.org> (raw)
In-Reply-To: <20210608202143.247427-1-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>
