This cannot work. I do not understand what you are trying to achieve with this.
I would like to avoid the extra dummy read that your patch proposes.
That's what I also tried. But from the ref manual I got no idea. When we do not find a hy to deassert the chip select manually, we cannot avoid this read.
It seems that the mainline linux only implements a GPIO based SPI driver. So we cannot take it for reference.
I'm wonderng how this works on the Denx' M28EVK.
