Applied to the togreg branch of iio.git and pushed out as testing for the autobuilders to play with it. If anyone wants to comment I won't be pushing out in a non rebasing form until at least next weekend.

To prepare for a future patch that will add a DT node for the ADC, make axp20x_adc able to probe from DT and get the per-variant data from of_device_id.data since platform_device_id.driver_data won't be set when probing by DT. Leave the ability to probe via platform for driver compatibility with old DTs.
