Date: Wed, 17 Sep 2014 17:57:58 +0800 From: Robin Gong <b38343@...escale.com> To: <robh+dt@...nel.org>, <pawel.moll@....com>, <mark.rutland@....com>, <ijc+devicetree@...lion.org.uk>, <galak@...eaurora.org>, <shawn.guo@...escale.com>, <kernel@...gutronix.de>, <sre@...nel.org>, <dbaryshkov@...il.com>, <dwmw2@...radead.org>, <grant.likely@...aro.org>, <linux@....linux.org.uk> CC: <devicetree@...r.kernel.org>, <linux-kernel@...r.kernel.org>, <linux-pm@...r.kernel.org>, <linux-arm-kernel@...ts.infradead.org> Subject: [PATCH v3 1/3] 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.
