[PATCH v5 6/9] dt-bindings: iio: add vref support to sd modulator

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Allow to specify the reference voltage used by the SD modulator.
When the SD modulator is defined as an IIO backend, the reference
voltage can be used to evaluate scaling information of the IIO device.
The reference voltage is not used otherwise.
