From 6606bc9dee63ad8cda2cc310d2ad5992673a785a Mon Sep 17 00:00:00 2001 From: Baolin Wang Date: Thu, 17 Aug 2017 14:50:36 +0800 Subject: pinctrl: Add sleep related state to indicate sleep related configs In some scenarios, we should set some pins as input/output/pullup/pulldown when the specified system goes into deep sleep mode, then when the system goes into deep sleep mode, these pins will be set automatically by hardware. That means some pins are not controlled by any specific driver in the OS, but need to be controlled when entering sleep mode. Thus we introduce one sleep state config into pinconf-generic for users to configure.
