From c60f58ef0b1bc39a3b1fee691a28916d1e2b84a8 Mon Sep 17 00:00:00 2001 From: Varun Wadekar <vwadekar@nvidia.com> Date: Mon, 28 Mar 2016 14:43:03 -0700 Subject: [PATCH] Tegra186: clear the system cstate for offline core This patch clears the system cstate when offlining a CPU core as we need to update the sytem cstate to SC7 only when we enter system suspend.
