Crate mcp23017

Manages an MCP23017, a 16-Bit I2C I/O Expander with Serial Interface module.

This operates the chip in IOCON.BANK=0 mode, i.e. the registers are mapped sequentially. This driver does not set IOCON.BANK, but the factory default is 0 and this driver does not change that value.

See the datasheet for more information on the device.
