A couple of weeks ago, Sekhar reported a warning issue happening in
CPPI 4.1. The teardown sequence was not correctly programmed.
The caused was a couple of difference between the DSPS and the DA8xx.
These differences are the way to program the autoreq, the teardown and
the DMA mode.
This series intends to fix the teardown and to correctly program
the DMA mode.
This series has been roughly tested.
I have only tried it on the DA580 LCK and the BeagleBone Black.
Only the device mode (msc and ecm) have been tested.
Changes in v2:
- Fix some typo (indentation and symbols name)
- Limit the number of channels to 4 for DA8xx
- Remove duplicated defines
