From e7fa1fb39b118cc8415a946fd2e6bc0f6b6c05c9 Mon Sep 17 00:00:00 2001 From: Anson Huang Date: Sun, 3 Jun 2018 10:33:45 +0800 Subject: ARM: imx: add cpu idle support for i.MX6SLL i.MX6SLL supports cpu idle with ARM power gated, it can reuse i.MX6SX's cpu idle driver to support below 3 states of cpu idle: state0: WFI; state1: WAIT mode with ARM power on; state2: WAIT mode with ARM power off. L2_PGE in GPC_CNTR needs to be cleared to support state2 cpu idle.
