Subject: [PATCH v8 0/4] This is the 1st version of suspend for RK3288.
Date: Sat, 15 Nov 2014 19:45:06 +0800 [thread overview]
Message-ID: <1416051910-16730-1-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-20141112. 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.
Based on:
[v5,1/6] ARM: rockchip: convert to regmap and use pmu syscon if available
https://patchwork.kernel.org/patch/5086341/
[v5,2/6] ARM: rockchip: add option to access the pmu via a phandle in smp_operations
https://patchwork.kernel.org/patch/5086441/
[v5,3/6] ARM: dts: rockchip: add pmu references to cpus nodes
https://patchwork.kernel.org/patch/5086351/
[v5,4/6] ARM: rockchip: add basic smp support for rk3288
https://patchwork.kernel.org/patch/5086371/
[v5,5/6] ARM: dts: rockchip: add intmem node for rk3288 smp support
https://patchwork.kernel.org/patch/5086361/
[v5,6/6] ARM: dts: rockchip: add reset for CPU nodes
https://patchwork.kernel.org/patch/5086381/
[v3] usb: dwc2: add bus suspend/resume for dwc2
https://patchwork.kernel.org/patch/5266281/
Changes in v8:
- use enum for define sleep mode
- move rk3288_config_bootdata to the front of sram memcpy
- add ddr pinctrl for suspend
- keep all except cpu&tp power rail on during suspend
- add regulator-on-in-suspend before set suspend voltage
- add a reference of ddrio_pwroff and ddr0_retention
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
