From: Michael Hennerich <michael.hennerich@xxxxxxxxxx> Changes since RFC/v1: IIO: Apply list review feedback Apply list review feedback: Rename attributes to fit IIO convention used in other drivers. Provide ddsX_out_enable as opposed to ddsX_out_disable. Fix typos. Changes since v2: IIO: dds.h: Apply more list review feedback Fix mixture of X and [n] notation for indices. Remove duplicated descriptions. Add store methods to some dds convenience macros.
