sorry, I have no idea what you mean and did there. To make the
chipselect right I suppose this part of spi subsystem, you don't need
(if you don't doing hacks) to touch anything at driver layer. What you
need is to tell the spi subsystem the right configuration so the spi
controller can do the right thing.
I also tried to google "Ralink MT7228" without luck.
Do you boot via device tree or the old way?
