Subject: [PATCH v4 0/4] pm: Add power off control
Date: Fri, 14 Dec 2012 11:33:13 +0530 [thread overview]
Message-ID: <1355464997-19367-1-git-send-email-anilkumar@ti.com> (raw)
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
