Subject: [PATCH v3 0/6] add suspend support for RK3288

From: Chris Zhong <zyw@...k-chips.com>

this is the 1st version of suspend. 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 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 (1):
  pinctrl: rockchip: add suspend/resume functions

Chris Zhong (5):
  pinctrl: rockchip: save and restore gpio6_c6 pinmux in suspend/resume
  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
