Subject: [PATCH RFC 2/2] arm64: dts: qcom: msm8953: Add GPU
Date: Thu, 25 Jan 2024 22:56:26 +0100 [thread overview]
Message-ID: <20240125-msm8953-gpu-v1-2-f6493a5951f3@z3ntu.xyz> (raw)
In-Reply-To: <20240125-msm8953-gpu-v1-0-f6493a5951f3@z3ntu.xyz>
From: Vladimir Lypak <vladimir.lypak@gmail.com>
Add the GPU node for the Adreno 506 found on this family of SoCs. The
clock speeds are a bit different per SoC variant, SDM450 maxes out at
600MHz while MSM8953 (= SDM625) goes up to 650MHz and SDM632 goes up to
725MHz.
To achieve this, create a new sdm450.dtsi to hold the 600MHz OPP and
use the new dtsi for sdm450-motorola-ali.
