From 8eaa9e42dab29507df70f58025f5e8b7dee17e19 Mon Sep 17 00:00:00 2001 From: Tomasz Figa Date: Sat, 15 Jun 2013 09:13:25 +0900 Subject: [PATCH] ARM: EXYNOS: Remove legacy power domain registration code This patch removes static definitions of power domains and code responsible for registering them and adding devices to them, since only DT based boot is now supported on Exynos.
