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
