Cover letter [PATCHv4 0/2] cppi41 dma fixes for v4.10-rc cycle
Hi all,
I'm using v4 naming here as the earlier patch "dmaengine: cppi41: Add dma support to da8xx" has been separated from the error -115 issue. We've identified so far three musb and cppi41 regressions:
1. Error -71 regression with musb
This is not dma related, and fixed with recently posted patch "[PATCH 1/2] usb: musb: Fix host mode error -71 regression".
2. Error -115 regression with cppi41 dma with musb
This regression was caused by commit 098de42ad670 ("dmaengine:
cppi41: Fix unpaired pm runtime when only a USB hub is connected") and causes runtime PM autosuspend delay to time out on active dma transfers when connecting a mass storage device to a usb hub. This is fixed in the first patch in this series.
3. Race with runtime PM and cppi41_dma_issue_pending()
This is really a separate issue from the error -115 problem, and fixed with the second patch in this series. That's minimal v4 version of the "dmaengine: cppi41: Fix oops in cppi41_runtime_resume" patch.
Regards,
Tony
