Add nodes for GPU (Mali 400) to Exynos4210 and Exynos4412. Describe the GPU as much as possible however still few elements are missing: 1. Exynos4210 bus clock is not described in hardware manual therefore the IP gate clock was provided, 2. Exynos4412: Not sure what to do with CLK_G3D clock responsible for gating entire IP block (it is now being disabled as unused), 3. Regulator supplies on Trats board. Limited testing on Odroid U3 (Exynos4412). 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) 3. Remove some of operating points to match Mali in Tizen kernel. Previously they were taken from datasheet but this information is too generic. 4. Add 533 MHz opp to Exynos4412-prime. --- arch/arm/boot/dts/exynos4.dtsi | 36 +++++++++++++++++++ arch/arm/boot/dts/exynos4210-origen.dts | 5 +++ arch/arm/boot/dts/exynos4210-trats.dts | 4 +++ .../boot/dts/exynos4210-universal_c210.dts | 5 +++ arch/arm/boot/dts/exynos4210.dtsi | 17 +++++++++ .../boot/dts/exynos4412-itop-scp-core.dtsi | 5 +++ arch/arm/boot/dts/exynos4412-midas.dtsi | 5 +++ .../boot/dts/exynos4412-odroid-common.dtsi | 5 +++ arch/arm/boot/dts/exynos4412-prime.dtsi | 7 ++++ arch/arm/boot/dts/exynos4412.dtsi | 25 +++++++++++++ 10 files changed, 114 insertions(+)
