From 4db0ba22da9f4406c292a6a6110eeb2edd12f16a Mon Sep 17 00:00:00 2001 From: Alexandre Belloni Date: Thu, 15 Jan 2015 15:59:27 +0100 Subject: ARM: at91: pm: prepare for multiplatform Split at91_pm_init() in three variants that are called by the respective SoCs .init_machine. This allows to remove the of_machine_is_compatible() calls and move at91_pm_init() out of arch_initcall() which is required for multiplatform.
