From 9467d298e92455e6fd411d7ef1f367ced940587c Mon Sep 17 00:00:00 2001 From: Laxman Dewangan Date: Wed, 1 Feb 2012 12:09:04 +0530 Subject: gpio: tps65910: Add sleep control support The device tps65910/tps65911 supports the sleep functionality in some of gpios. If gpio is configured in output mode and sleep is enabled then during device sleep state, the output of gpio becomes LOW regardless of non-sleep output value. Such gpio can be used to control regulator switch such that output of regulator is off in device sleep state.
