gxio
— driver for
Gumstix onboard I/O interface
gxio* at pxaip?
options GXIO_BLUETOOTH_ON_HWUART
options GXIO_DEFAULT_EXPANSION
The gxio
driver supports several different
expansion boards. Those boards have to be configured either by kernel option
or using boot time parameter. The supported extension boards is system
specific.
gxio
is available for XScale based Gumstix
boards. To setup the expansion board on boot the parameter
“expansion” can be used. Additionally, some XScale systems can
connect two expansion boards. The second board can be configured by the
“busheader” boot parameter. The gxio
driver does not verify validity of both parameters.
For Xscale boards the following drivers are available for the peripherals:
GXIO_BLUETOOTH_ON_HWUART
The option only affects Xscale PXA250 based Gumstix boards. If set, the serial port HWUART is used to control Bluetooth module. Otherwise no Bluetooth module is configured for PXA250 boards.
GXIO_DEFAULT_EXPANSION
If configured, the gxio
of the
processor is setup for the board. If a boot parameter is used, the boot
value is used instead.
For Xscale based boards the following values are supported:
basix |
cfstix |
etherstix |
netcf |
netcf-vx |
netduo |
netduo-mmc |
netmicrosd |
netmicrosd-vx |
