Hence, gpio_get_value() should be left unchanged (using PSR in all cases), and SION should be set for all GPIOs in the i.MX6 pin definition header files.
I just does not follow why this preferred against Fabio's proposed patch to read from DR?
Because in case of a level conflict between the GPIO output and some other hardware on the board, one would expect gpio_get_value() to return the actual pin level, and not the level that the GPIO output tries (but possibly fails) to apply on this pin.
Ahh now I see. I agree :-)
