Subject: [PATCH 0/7 v3] K3DMA fixes for HiKey HDMI audio
Date: Wed, 20 Jul 2016 20:53:02 -0700 [thread overview]
Message-ID: <1469073189-9167-1-git-send-email-john.stultz@linaro.org> (raw)
Per Mark's suggestion, I've split out the k3dma changes
on their own as they are mostly fixes and the addition
of cyclic mode.
New in v3:
* With inspiration from YongQin Liu, I figured out the reason we
were seeing occasional DMA ERR issues: The desc structures were
being allocated with kzalloc and so changes weren't necessarily
being flushed to memory before the transfers started. I fixed
this, but also uncoverd a memory leak that was happening in
cyclic mode, so I fixed that as well.
Thoughts and comments would be appreciated!
thanks
