[RFC PATCH 0/3] DMAengine: Add support for Immediate commands

[Sireesh Kodali <sireeshkodali1@gmail.com>]

The IPA v2.x block, found on some older Qualcomm SoCs, uses BAM DMA to
send and receive packets from the AP. It also uses BAM to receive
commands from the AP (and possibly the modem). These commands are
encoded as "Immediate Commands". They vary from regular BAM DMA
commands, although I'm not sure as to exactly how they vary. Adding
support for immediate commands is trivial, but requires also adding
Immediate Commands to the dmaengine API, which is what this patch does.
