Hello,
I had the feeling that the MXS SPI driver was rather useless due to the SPI being only
half-duplex on i.MX28, but it looks like people's using it so I was wondering what
kind of SPI devices can be driven with it, or if there is any trick that allows
bi-directional communication.
Thanks,

It can't do full duplex. I tested it with master-slave communication (half-
duplex) and various SPI flashes.
