Subject: [PATCH] ARM: dts: exynos5420: add mali dt bindings and enable mali on Odroid XU3/4
Date: Tue, 29 Oct 2019 11:43:12 +1030 [thread overview]
Message-ID: <20191029011312.4601-1-mihailescu2m@gmail.com> (raw)
Add device tree bindings for Mali GPU for Exynos 542x SoC.
GPU is disabled by default, and is enabled for each board after the regulator
is defined. Tested on Odroid-XU4.
