PATCH 2.6: tms380tr update: move to DMA API
From: Jochen Friedrich
Date: Sat Jul 23 2005 - 05:26:55 EST
Hi Jeff,
this patch makes tms380tr use the new DMA API. Now that on Alpha, this API
also supports bus master DMA for ISA (platform) devices, i changed the
driver to use this new API.
This also works around a bug in the firmware loader: The example provided
in Documentation/firmware_class no longer works, as the firmware loader
now calls get_kobj_path_length() and the kernel promptly oopses, as the
home-grown device doesn't have a parent. Of course, this doesn't happen
with a "real" device which has its bus (or pseudo bus in the case of
platform) as parent.
Signed-off-by: Jochen Friedrich <jochen@xxxxxxxx>
Converted tms380tr to use new DMA API:
- proteon.c, skisa.c: use platform pseudo bus to create a struct device
- Space.c: delete init hooks
- abyss.c, tmspci.c: pass struct device to tms380tr.c
- tms380tr.c, tms380tr.h: new DMA API, use real device fo firmware loader
