[PATCH 0/6] IIO driver for MCP3550/1/3

[Lukas Wunner <lukas@wunner.de>]

Two fixes, one speedup & one cleanup for the mcp320x.c driver,
plus support for new chips:

The MCP3550/1/3 are 22 bit delta-sigma ADCs with high accuracy,
low noise characteristics and an extended temperature range.
It's the top-of-the-line SPI ADC in Microchip's portfolio.

The chip is used by the "Revolution Pi" family of open source PLCs
based on the Raspberry Pi (https://revolution.kunbus.com/).

Thanks,

Lukas
