> Add support for the GPIO controller found on some QIXIS FPGAs in
> Layerscape boards such as LX2160ARDB and LS1046AQDS. This driver is

> A GPIO controller has a maximum of 8 lines (all found in the same
> register). Even within the same controller, the GPIO lines' direction is
> fixed, which mean that both input and output lines are found in the same

> added .fixed_direction_output bitmap to represent the true direction of
