[PATCH 03/08] ARM: shmobile: Make EMEV2 platform devices more compact
Magnus Damm
magnus.damm at gmail.com
Tue Jul 2 05:27:49 EDT 2013
From: Magnus Damm <damm at opensource.se>
Convert the EMEV2 SoC device setup code from using very
verbose resources and static platform devices to the
same style as more recent boards. This reduces the size
of the code.
