Subject: [PATCH v2 4/7] arm64: dts: exynos: Add GPU/Mali T760 node to Exynos7
Date: Fri, 21 Jun 2019 20:02:05 +0200	[thread overview]
Message-ID: <20190621180208.25361-4-krzk@kernel.org> (raw)
In-Reply-To: <20190621180208.25361-1-krzk@kernel.org>

Add nodes for GPU (Mali T760) to Exynos7.  Current support for Exynos7
misses a lot, including proper clocks, power domains, frequency and
voltage scaling and cooling.  However this still can provide basic GPU
description.  Not tested on HW.
