Subject: [RFT 04/10] ARM: dts: exynos: Add GPU/Mali 400 node to Exynos3250
Date: Tue, 18 Jun 2019 21:05:28 +0200 [thread overview]
Message-ID: <20190618190534.4951-5-krzk@kernel.org> (raw)
In-Reply-To: <20190618190534.4951-1-krzk@kernel.org>
Add nodes for GPU (Mali 400) to Exynos3250. This is still limited and
not tested:
1. No dynamic voltage and frequency scaling,
2. Not sure what to do with CLK_G3D clock responsible for gating entire
IP block (it is now being disabled as unused).
