pxaip
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 gpio(4)
interface. The driver supports GPIO_PIN_INPUT
and
GPIO_PIN_OUTPUT
. GPIO pins being used in alternate
configurations are not available for GPIO operations.
The pxaip
driver first appeared in
NetBSD 2.0. GPIO attachment appeared in
NetBSD 8.0.
