Hello,
This series adds AC97 audio support for Cirrus Logic EP93xx family SoCs. Example machine driver is for Simplemachines Sim.One (which is the only hardware that I have which has AC97 codec).
The first patch is a bugfix for the DMA code. Without the patch audio DMA transfers may corrupt if playing application is killed while playing. This results weird noise playback when application is started again. I would like Ryan Mallon to confirm that this is indeed correct fix and if possible to check that I2S transfers still work after this patch is applied.
Please review.
Changes to previous revision: - patches are taken from the correct branch so they should apply on top of latest mainline - increased cold reset sleep time
Thanks, MW
