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). These patchs are based on linux-next. Changes from v3: - TPS65217 mfd driver changes are accepted so dropped from this series. - With recent changes in the kernel, reboot_mutex held BUG() is not seen so removed while(1); from rtc_power_off. - Removed spinlock before while(1); which is not necessary. 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 (1): rtc: OMAP: Add system pm_power_off to rtc driver Documentation/devicetree/bindings/rtc/rtc-omap.txt | 5 ++ arch/arm/boot/dts/am335x-bone.dts | 6 ++ arch/arm/configs/omap2plus_defconfig | 1 + drivers/rtc/rtc-omap.c | 74 +++++++++++++++++++- 4 files changed, 85 insertions(+), 1 deletion(-) -- 126.96.36.199 -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
