Subject: [PATCH v3 00/12] dmaengine: at_xdmac: Various fixes
Date: Wed, 15 Dec 2021 13:01:03 +0200 [thread overview]
Message-ID: <20211215110115.191749-1-tudor.ambarus@microchip.com> (raw)
Bugs identified when debugging a hang encountered when operating
an octal DTR SPI NOR memory. The culprit was the flash, not the
DMA driver, so all these bugs are not experienced in real life,
they are all theoretical fixes. Nevertheless the bugs are there
and I think they should be squashed.
Tested the serial with DMA on sama5d2_xplained. Tested QSPI with DMA on
sama7g5ek. All went well.
v3:
- drop tty patches, they were applied by Greg.
- improve all commit descriptions
- split v2's patch 13/13 in two: one removing a level of indentation
and one fixing the race.
v2:
- drop local chan_rx local variable in patch 3/13, focus just on fixes
for now.
- collect Richard's Acked-by tag.
- add details in the cover letter about what tests were performed.
