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@kernel.org> --- Changes since v1: 1. Use samsung,exynos4210-mali compatible 2. Use CLK_G3D as bus clock (clock for entire IP block) --- arch/arm/boot/dts/exynos3250-artik5.dtsi | 5 ++++ arch/arm/boot/dts/exynos3250-monk.dts | 5 ++++ arch/arm/boot/dts/exynos3250-rinato.dts | 5 ++++ arch/arm/boot/dts/exynos3250.dtsi | 33 ++++++++++++++++++++++++ 4 files changed, 48 insertions(+)
