Add device tree node for Mali GPU for Exynos 542x SoC. GPU is disabled by default, and is enabled for each board after the regulator is defined. Tested on Odroid-XU4. Changes since v2: - separate patch for bindings - fixed bindings typo Changes since v1: - used generic node and label for GPU - added bindings for compatible - fixed irq indentation - fixed interrupt-names to match bindings - added cooling cells for future TMU connection - used generic node and label for GPU opp table - removed always-on from SoC GPU regulator Signed-off-by: Marian Mihailescu <mihailescu2m@gmail.com> --- arch/arm/boot/dts/exynos5420.dtsi | 50 +++++++++++++++++++++++++++ arch/arm/boot/dts/exynos5422-odroid-core.dtsi | 6 +++- 2 files changed, 55 insertions(+), 1 deletion(-)
