Subject: [PATCH v2 0/2] iio: dac: ad5770r: dt bindings fixes

From: Alexandru Tachici <[email protected]>

This aims to replace use of num property from dt nodes with
reg property both in dt bindings and driver and fix
dt bindings errors.

1. read from fwnode reg property instead of num property

2. replace num property with reg property and fix dt
bindings errors

Changelog v1 -> v2:
- replaced "oneOf:" with items for adi,range-microamp
- added reg allowed values to each channel

This one is awkwardly timed - I'll be doing a fixes pull request shortly
then advance my fixes branch to include the patch this fixes.

Please poke me if I look like I've forgotten it!
Now we are out of sync with the bindings but as long as we get the fix
in before the release that shouldn't really matter to anyone.

Thanks,

Jonathan
