Subject: [PATCH 3/4] arm64: dts: rockchip: Add GPU node for rk3568
Date: Fri, 30 Jul 2021 13:45:14 -0300	[thread overview]
Message-ID: <20210730164515.83044-4-ezequiel@collabora.com> (raw)
In-Reply-To: <20210730164515.83044-1-ezequiel@collabora.com>

Rockchip SoCs RK3566 and RK3568 have a Mali Gondul core
which is based on the Bifrost architecture. It has
one shader core and two execution engines.

Quoting the datasheet:

Mali-G52 1-Core-2EE
* Support 1600Mpix/s fill rate when 800MHz clock frequency
* Support 38.4GLOPs when 800MHz clock frequency
