[PATCH 00/11] iio: adc: ad7606: improvements and ad7606c parallel interface support

[David Lechner <dlechner@baylibre.com>]

The main purpose of this series is to add support for the AD7606C chips
using a parallel interface. Along the way quite a few improvements were
made to the driver which in the end made adding the additional chips
trivial.

The first 3 patches are fixes. The next 6 are some minor cleanups. The
2nd to last patch is the big one. As explained in the respective commit
message, the channel data structures were getting out of hand and only
going to get worse with the addition of SPI offload support. Instead, we
are opting to dynamically allocate the channel data structures to avoid
a bunch of the existing complexity in the driver.

I have limited access to hardware, so I was only able to test this with
ad7606c-18.
