I/O Control using mts-io Package

Most of the peripheral I/O on the MTCDP is accessible through the mts-io package. This package provides a device driver (mts_io) which exposes a sysfs interface to the user at /sys/devices/platform/mtcdp. You can control the I/O directly by manipulating the files in this directory, or you can use the provided sysfs wrapper program (mts-io-sysfs). mts-io-sysfs is just a bash script which reads from and writes to files in the sysfs platform directory.
