Add intial PMU settings for exynos7. This is required for future suspend-to-ram and cpuidle support. Signed-off-by: Eunseok Choi <es10.choi@xxxxxxxxxxx> Signed-off-by: Abhilash Kesavan <a.kesavan@xxxxxxxxxxx> --- This patch has been tested on an Exynos7 espresso board and is based on Kgene's tree (for-next branch). Following are the dependencies: 1) Support 64bit Cortex A57 based Exynos7 SoC http://www.spinics.net/lists/arm-kernel/msg357380.html 2) mfd: syscon: Decouple syscon interface from syscon devices http://www.spinics.net/lists/linux-samsung-soc/msg35906.html 3) ARM: EXYNOS: Add platform driver support for Exynos PMU http://lists.infradead.org/pipermail/linux-arm-kernel/2014-July/275675.html 4) ARM: EXYNOS: Move PMU specific definitions from common.h http://lists.infradead.org/pipermail/linux-arm-kernel/2014-July/270655.html 5) ARM: EXYNOS: Move pmu specific header files under "linux/mfd/samsung" https://lkml.org/lkml/2014/4/28/217 6) drivers: mfd: Add support for Exynos PMU driver https://lkml.org/lkml/2014/4/28/332 NOTE: The above dependencies are not final yet, especially the movement of exynos pmu driver to the mfd directory. I will re-work this patch when the final location for exynos PMU driver is decided. .../devicetree/bindings/arm/samsung/pmu.txt | 1 + arch/arm64/boot/dts/exynos7.dtsi | 5 + drivers/mfd/exynos-pmu.c |
