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.
