Subject: [PATCH v2 1/7] ARM: dts: exynos: Add GPU/Mali 400 node to Exynos3250
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).
Signed-off-by: Krzysztof Kozlowski <krzk@...nel.org>
---
Changes since v1:
1. Use samsung,exynos4210-mali compatible
2. Use CLK_G3D as bus clock (clock for entire IP block)
