[PATCH v3 00/10] iio: dac: ad5446: Refactor and add support for AD5542

["Nuno Sá via B4 Relay" <devnull+nuno.sa.analog.com@kernel.org>]

Alright, what was suposed to be a simple one liner patch ended up being
a full refactor (modernization) of the whole thing :). I think the
changes are anyways fairly simple so hopefully nothing was broken.

I'm also aware of the checkpatch failure in Patch 6 ("iio: dac: ad5446:
Separate I2C/SPI into different drivers") but I'm really not seeing the
added value of adding the kconfig help text to the core symbol.
