From 98a7f813e9c984afaf09c651b160dd3c2a66b22e Mon Sep 17 00:00:00 2001 From: Keerthy Date: Mon, 28 Nov 2016 09:31:58 +0530 Subject: Documentation: pinctrl: palmas: Add ti,palmas-powerhold-override property definition commit 0ea66f76ba17a4b229caaadd77de694111b21769 upstream. GPIO7 is configured in POWERHOLD mode which has higher priority over DEV_ON bit and keeps the PMIC supplies on even after the DEV_ON bit is turned off. This property enables driver to over ride the POWERHOLD value to GPIO7 so as to turn off the PMIC in power off scenarios.
