Subject: [PATCH linux-next v2 0/1] dmaengine: at_hdmac: fix residue computation
Date: Thu, 18 Jun 2015 13:25:40 +0200 [thread overview]
Message-ID: <cover.1434626239.git.cyrille.pitchen@atmel.com> (raw)
ChangeLog
v2:
- rework the processing of the linked list of DMA descriptors to take a
race condition risk into account. See patch comments for more details on
why we have chosen this implementation.
v1:
This patch fixes a bug reported by Jiri Prchal for the USART behaviour on
some Atmel SoCs when DMA is used to receive data. More generally, it fixes
the DMA residue computation.
