first of all, thank you very much for this series.

Eric has no time as maintainer, so i will try to give you some feedback (beware of very little audio driver knowledge).

I functionally tested your patch series on a Raspberry Pi 1 B (bcm2835_defconfig), so this whole series is at least:

Tested-by: Stefan Wahren <stefan.wahren@xxxxxxxx>

Unfortunately there is still an corruption issue with underlying vchiq and multi_v7_defconfig, so no wider tests.

I don't know if you tested this series on a Raspberry Pi. Maybe you have some specific scenarios, which should be tested.

As a reviewer i have some suggestions, but only trivia. I don't know if it's a problem that this series hasn't been send to devel@xxxxxxxxxxxxxxxxxxxx
