From 422b06769eacdf068142afc4d69e1e0a591a19d7 Mon Sep 17 00:00:00 2001 From: Robin Gong Date: Wed, 12 Nov 2014 16:20:37 +0800 Subject: [PATCH] ARM: dts: imx6: add pm_power_off support for i.mx6 chips 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.
