[PATCH v9 02/17] iio: ABI: raw, scale and offset for frequency/phase channels

[Rodrigo Alencar via B4 Relay]

From: Rodrigo Alencar <rodrigo.alencar@xxxxxxxxxx>

Consider scale and offset attributes for frequency and phase channels.
Frequency channels are going to be introduced later alongside a DDS device
driver which is going to leverage those new attributes.
