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.
The pxaip
driver was written by Steve
