From cd42145cd993fa1a7426d63648fc7e3423fb2e1d Mon Sep 17 00:00:00 2001 From: Alexandre Courbot Date: Fri, 7 Feb 2014 13:35:04 +0900 Subject: [PATCH] ARM: firmware: add prepare_idle() operation Some firmwares do not put the CPU into idle mode themselves, but still need to be informed that the CPU is about to enter idle mode before this happens. Add a prepare_idle() operation to the firmware_ops structure to handle such cases.
