Add PM power_off control to rtc driver and PMIC status is set to STATUS_OFF to shutdown PMIC if PWR_EN is toggled by RTC module.
System power off sequence:- * Set PMIC STATUS_OFF when PMIC_POWER_EN is pulled low * Enable PMIC_POWER_EN in rtc module * Set rtc ALARM2 time * Enable ALARM2 interrupt These patches were tested on am335x-bone (BeagleBone). First patch is based on linux-next, second patch is based on mfd/master and rest of the patches are based on linux-omap master. Changes from v2: - Incorporated Kevin's comment on v2 * Enabled RTC in ompa2plus_defconfig Changes from v1: - Incorporated Vaibhav's comments on v1 * Changed the time rollover logic with the help of rtc-lib APIs AnilKumar Ch (3): ARM: dts: AM33XX: Set pmic-shutdown-controller for BeagleBone ARM: dts: AM33XX: Enable system power off control in am335x-bone ARM: OMAP2+: omap2plus_defconfig: Enable RTC support Colin Foe-Parker (2): rtc: OMAP: Add system pm_power_off to rtc driver mfd: tps65217: Set PMIC to shutdown on PWR_EN toggle .../devicetree/bindings/regulator/tps65217.txt | 4 + Documentation/devicetree/bindings/rtc/rtc-omap.txt | 5 ++ arch/arm/boot/dts/am335x-bone.dts | 6 ++ arch/arm/configs/omap2plus_defconfig | 1 + drivers/mfd/tps65217.c | 12 +++ drivers/rtc/rtc-omap.c | 81 +++++++++++++++++++- 6 files changed, 108 insertions(+), 1 deletion(-) -- 1.7.9.5 _______________________________________________ devicetree-discuss mailing list devicetree-discuss@lists.ozlabs.org https://lists.ozlabs.org/listinfo/devicetree-discuss
