RE: [PATCH v3 2/2] dt-bindings: iio: frequency: add admv1013 doc

["Miclaus, Antoniu" <Antoniu.Miclaus@xxxxxxxxxx>]

Hello Rob,

These properties are fixed and available in the datasheet (binary format):
https://www.analog.com/media/en/technical-documentation/data-sheets/ADMV1013.pdf

Please see Page 37 of 39, Table 15, QUAD_SE_MODE.

Regards,
