Subject: [PATCH] ARM: mach-shmobile: UIO platform data for sh7372/ap4evb V2
Date: Thu, 14 Oct 2010 09:24:48 +0000 [thread overview]
Message-ID: <20101014092448.2053.2951.sendpatchset@t400s> (raw)
From: Magnus Damm <damm@opensource.se>
Export the following sh7372 multimedia hardware blocks
using UIO: VPU, VEU[0-3], JPU and SPU2DSP[0-1]
The amount of physically continguous memory assigned to
each hardware block can be configured using the kernel
command line option "memchunk".
