You need to differentiate between Vybrid and i.MX: Vybrid muxes a pin to GPIO on gpio_request_one (via .gpio_request_enable callback) i.MX does not mux a pin as GPIO on its own, but needs to be muxed explicitly. That has been always the case... I don't know what behavior is right, it is just "different"...
Hmm, I think What Vybrid and Tegra have done is better, but it would be better to get inputs from Linus, which you already asked for :) -- viresh
