This kernel module creates the
/sys/devices/platform/mts-io enumeration
of the features for MTAC MFSER boards.

This driver requires the mtac.ko driver
loaded first.  depmod should take care
of this.

Documentation for this board is here:

http://www.multitech.net/developer/software/mlinux/using-mlinux/mlinux-using-accessory-cards/mtac-mfser-usage/

An init script can look in:
/lib/modules/$(uname -r)/extra/mtac_mfser.ko

to find the driver.


The mtac-mfser v2.0.0 driver is based on v1.1.1,
with the legacy kernel gpio library replaced
with gpiod.

v1.1.2 was a stopgap before gpiod could be implemented
in mts-io and mtac drivers.
