[PATCH v2 0/6] IIO driver for MCP3550/1/3

[Lukas Wunner <lukas-JFq808J9C/izQB+pC5nmwQ@public.gmane.org>]

One speedup, one cleanup, one kerneldoc patch for mcp320x.c
plus support for the MCP3550/1/3 used by the "Revolution Pi"
family of open source PLCs (https://revolution.kunbus.com/).

Changes since v1:
- Drop two patches which are now queued. (Jonathan)

- Move kerneldoc to separate patch. (Jonathan)

- Move support for continuous conversion mode to separate patch
  which is marked informational / not for merging.  Rename device
  property to "continuous" for consistency with the existing
  similar property of drivers/iio/light/us5182d.c. (Rob, Jonathan)

- Rework calculation of raw value in patch [5/6]:  Instead of
  byte-wise mangling, convert the big endian value clocked out
  by the chip to host byte order and mangle the resulting 32-bit
  value.  Reduces the amount of code and improves readability as
  the bit numbers referenced in the code comment and datasheet
  are used verbatim in the code.

- Use switch/case-statement instead of if-clause when applying
  chip-specific quirks in mcp320x_probe(). (Jonathan)

- Expand code comment explaining the two consecutive conversions
  in mcp320x_probe(). (Jonathan)

Thanks,

Lukas
