From 86d7cb0bc8fd0c638d7aa407096e8cb122c5fd6a Mon Sep 17 00:00:00 2001 From: Peter 'p2' De Schrijver Date: Mon, 20 Oct 2008 11:37:55 +0300 Subject: [PATCH] Generic twl4030 power script for 3430 based boards. This is a generic twl4030 power script for 3430 based boards. It handles sleep and wakeup events. In case of a sleep event it will first put the Reset and Control (RC) resources to sleep and then put the voltage regulators to sleep. In case of a wakeup event, the system clock will be started first, then the voltage regulators will be woken up and finally the RC resources will be woken up.
