RK3288 can shut down the cpu, gpu and other device controllers in suspend, and it will pull the GLOBAL_PWROFF pin to high in the final stage of the process of suspend, pull the pin to low again when resume. Changes in v7: - get rid all of unused code - add regulator-state-mem sub node for suspend Changes in v6: - modify comments - get rid of the save/restore of SRAM - doing the copy of resume code once at init time - remove ROCKCHIP_ARM_OFF_LOGIC_DEEP from rk3288_fill_in_bootram - add of_platform_populate in rockchip_dt_init - change pmu_intmem@ff720000 to sram@ff720000 - change pmu_intmem@ff720000 to sram@ff720000 Changes in v5: - modify comments - use rk3288_bootram_sz for memcpy size - fixed error of sram save and restore - change the size of sram in example - change size to 4k Changes in v4: - remove grf regmap Changes in v3: - move the pinmux of gpio6_c6 save and restore to pinctrl-rockchip Changes in v2: - __raw_readl/__raw_writel replaced by readl_relaxed/writel_relaxed - add the regulator calls in prepare and finish. - add the pinmux of gpio6_c6 save and restore - put "rockchip,rk3288-pmu-sram" to first Chris Zhong (5): clk: rockchip: RK3288: add suspend and resume ARM: rockchip: add suspend and resume for RK3288 ARM: rockchip: Add pmu-sram binding ARM: dts: add RK3288 suspend support ARM: dts: add suspend voltage setting for RK808 .../devicetree/bindings/arm/rockchip/pmu-sram.txt | 16 ++ arch/arm/boot/dts/rk3288-evb-rk808.dts | 46 +++- arch/arm/boot/dts/rk3288.dtsi | 11 + arch/arm/mach-rockchip/Makefile | 1 + arch/arm/mach-rockchip/pm.c | 264 +++++++++++++++++++++ arch/arm/mach-rockchip/pm.h | 99 ++++++++ arch/arm/mach-rockchip/rockchip.c | 2 + arch/arm/mach-rockchip/sleep.S | 73 ++++++ drivers/clk/rockchip/clk-rk3288.c | 60 +++++ 9 files changed, 571 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/arm/rockchip/pmu-sram.txt create mode 100644 arch/arm/mach-rockchip/pm.c create mode 100644 arch/arm/mach-rockchip/pm.h create mode 100644 arch/arm/mach-rockchip/sleep.S -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
