|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
is an on-board GPIO controller found in XScale PXA250, PXA255, PXA270,
|
|
PXA271, PXA272, and PXA273 processors manufactured by Intel and Marvell
|
|
Technology.
|
|
The driver supports 86 pins for PXA250 or 121 pins for PXA270
|
|
processor families.
|
|
Access to the pins is provided by the
|
|
.Xr gpio 4
|
|
interface.
|
|
The driver supports
|
|
.Dv GPIO_PIN_INPUT
|
|
and
|
|
.Dv GPIO_PIN_OUTPUT .
|
|
GPIO pins being used in alternate configurations are not available
|
|
for GPIO operations.
