Subject: [PATCH v5 2/5] arm64: dts: rockchip: add gpu node to rk356x

From: Ezequiel Garcia <[email protected]>

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
