From 05136f0897b526b9cd090c93b95bbd1b67c18cc5 Mon Sep 17 00:00:00 2001 From: Anson Huang Date: Wed, 17 Dec 2014 12:24:12 +0800 Subject: ARM: imx: support arm power off in cpuidle for i.mx6sx This patch introduces an independent cpuidle driver for i.MX6SX, and supports arm power off in idle, totally 3 levels of cpuidle are supported as below: 1. ARM WFI; 2. SOC in WAIT mode; 3. SOC in WAIT mode + ARM power off. ARM power off can save at least 5mW power. This patch also replaces imx6q_enable_rbc with imx6_enable_rbc.
