Still missing a way to provide default modes and settings
for the driver from dt, but I see this as a start.

Hi,
Thanks for the patch.
:-)

This needs to set the ID for the device type, so that the driver gets
instantiated for the correct devicetype. And in the probe function check if
the driver was probed via DT (by checking spi->dev.of_node) and if it does
get the ID from the of_device_id rather the spi_device_id.
I was planning on doing that.
And I was experimenting with providing modes and settings for every
channel from the dt.
Is the DAC the only output devices in IIO?
I will send an proposal tomorrow :-) And thereby (maybe) pave the way
for the runtime mode switching
Should we drop the platform data support and only rely on dt?
