dmaengine: edma: Use vchan_terminate_vdesc() instead of desc_free

dmaengine: edma: Implement protection for invalid max_burst

2017-10-12T16:43:06+00:00

the device's max_burst to 32767 (CIDX is 16bit signed value) so clients can take this into consideration when setting up the transfer. During slave transfer preparation check if the requested maxburst is valid. Signed-off-by: Peter Ujfalusi Signed-off-by: Vinod Koul

dmaengine: edma: Align the memcpy acnt array size with the transfer

2017-09-21T17:21:07+00:00

Memory to Memory transfers does not have any special alignment needs regarding to acnt array size, but if one of the areas are in memory mapped regions (like PCIe memory), we need to make sure that the acnt array size is aligned with the mem copy parameters. Before "dmaengine: edma: Optimize memcpy operation" change the memcpy was set up in a different way: acnt == number of bytes in a word based on __ffs((src | dest | len), bcnt and ccnt for looping the necessary number of words to comlete the trasnfer. Instead of reverting the commit we can fix it to make sure that the ACNT size is aligned to the traswnfer.

dmaengine: edma: re-initialize dummy slot during system resume

2016-11-30T03:25:05+00:00

The last param set in a transfer should always be pointing to dummy param set in non-cyclic mode. When system wakes from low power state EDMA PARAM slots may be reset to random values. Hence, re-initialize dummy slot to dummy param set on system resume. Signed-off-by: Vignesh R Acked-by: Peter Ujfalusi Signed-off-by: Vinod Koul
