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 v5:
- reset-author
- use "__maybe_unused" annotation
- add pinctrl_force_default() in the error case
- 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:
- use SIMPLE_DEV_PM_OPS for suspend/resume struct
- 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
