Subject: [PATCH] arm64: dts: imx8mm: Add GPU node
Date: Thu, 22 Oct 2020 12:16:39 -0500 [thread overview]
Message-ID: <20201022171639.773702-1-aford173@gmail.com> (raw)
According to the documentation from NXP, the i.MX8M Nano has a
Vivante GC7000 Ultra Lite as its GPU core.
With this patch, the Etnaviv driver presents the GPU as:
etnaviv-gpu 38000000.gpu: model: GC7000, revision: 6203
It uses the GPCV2 controller to enable the power domain for the GPU.
