From f0c4ac1329452e5d31a03b4bb711c330065c0369 Mon Sep 17 00:00:00 2001 From: Joseph Lo Date: Fri, 11 Oct 2013 17:58:38 +0800 Subject: ARM: tegra: add LP1 support code for Tegra124 The LP1 suspend procedure is the same with Tegra30 and Tegra114. Just need to update the difference of the register address, then we can continue to share the code.
