Subject: [PATCH v9 0/4] The 1st version of suspend for RK3288.
Date: Tue, 25 Nov 2014 15:32:19 +0800	[thread overview]
Message-ID: <1416900743-29204-1-git-send-email-zyw@rock-chips.com> (raw)

This suspend patch is only support cut off the power of cpu and some external
devices, since we still lack power_domain driver, so the other power rail
of rk3288 need keep power on.
I have tested it on rk3288-evb board, atop next-20141124. goto suspend by type
"echo mem > /sys/power/state", vdd_cpu is about 0mv by measuring, so it can be
determined in sleep mode, then press power button to wakeup it.

Changes in v9:
- fold Doug's patches
- modify some print log
- update the subject and description

Changes in v8:
- use enum for define sleep mode
- move rk3288_config_bootdata to the front of sram memcpy
- set vdd_gpu to 1.0v during suspend
- add regulator-on-in-suspend before set suspend voltage

Changes in v7:
- get rid all of unused code
- add regulator-state-mem sub node for suspend

Changes in v6:
- 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:
- 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:
- add the regulator calls in prepare and finish.
- add the pinmux of gpio6_c6 save and restore
- put "rockchip,rk3288-pmu-sram" to first
