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 at ff720000 to sram at ff720000
- change pmu_intmem at ff720000 to sram at 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
