Subject: [PATCH v3 1/3] ARM: dts: imx6: add pm_power_off support for i.mx6 chips
Date: Wed, 17 Sep 2014 17:57:58 +0800 [thread overview]
Message-ID: <1410947881-7345-2-git-send-email-b38343@freescale.com> (raw)
In-Reply-To: <1410947881-7345-1-git-send-email-b38343@freescale.com>
All chips of i.mx6 can be powered off by programming SNVS.
For example :
On i.mx6q-sabresd board, PMIC_ON_REQ connect with external
pmic ON/OFF pin, that will cause the whole PMIC powered off
except VSNVS. And system can restart once PMIC_ON_REQ goes
high by push POWRER key.
