[PATCH v2 2/4] ARM: S5PV310: Add platform device and helper functions for FIMD
Sangbeom Kim

Thu Oct 21 00:27:54 EDT 2010
From: Jonghun Han <jonghun.han at samsung.com>
This patch adds platform device s5p_device_fimd0 for S5PV310 FIMD0.
S5PV310 has two FIMDs(FIMD0, FIMD1). FIMD1 will be added later.
Some definitions used to enable S5PV310 FIMD0 are added.
