v1: Initial patch version, to enable DMA mode on Intel Keembay platform
by exposing some dmaengine api to work around DMA limitations at the
client driver level.
This patchset suggests an ALSA-only quirk, having other more generic
means to deal with this limitation would be fine - we just wanted to
have a discussion on preferred directions. The IPs used are not
Intel-specific so sooner or later someone else will have similar
limitations to work-around.
