Revision 46cb52ad414ac829680d0bb8cc7090ac2b577ca7 authored by Linus Walleij on 15 July 2018, 20:09:29 UTC, committed by Jens Axboe on 27 August 2018, 20:25:54 UTC
The DMA is broken on this specific device for some unknown reason (probably badly designed or plain broken interface electronics) and will only work with PIO. Other users of the same hardware does not have this problem. Add a specific quirk so that this Gemini device gets DMA turned off. Also fix up some code around passing the port information around in probe while we're at it. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Jens Axboe <axboe@kernel.dk>
