Subject: [PATCH v3 2/3] ARM: dts: rockchip: Add GPU node for RK3128
Date: Mon, 4 Dec 2023 16:35:46 +0100 [thread overview]
Message-ID: <20231204153547.97877-3-knaerzche@gmail.com> (raw)
In-Reply-To: <20231204153547.97877-1-knaerzche@gmail.com>
RK3128 SoCs have Mali400 MP2 GPU.
Add the respective device tree node and the correspondending opp-table.
The frequencies and voltages of the opp-table have been taken from
downstream kernel.
