There's no point in keeping these around, they've been broken for some time, and the dmaenging/async_tx framework provides a far more reasonable interface. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

This allows you to specify the number of channels that the on-chip
|
|
DMAC supports. This will be 4 for SH7750/SH7751 and 8 for the
|
|
SH7750R/SH7751R.

|
|
This allows you to forcibly update the maximum number of supported
|
|
DMA channels for a given board. If this is unset, this will default
|
|
to the number of channels that the on-chip DMAC has.

help
|

This allows you to specify the maximum number of DMA channels to
|
|
support. Setting this to a higher value allows for cascading DMACs
|
|
with additional channels.

The DMABRG does data transfers from main memory to Audio/USB units
|
|
of the SH7760.
|
|
Say Y if you want to use Audio/USB DMA on your SH7760 board.
