From ffc7c5172a6d1f7ec468066a7172ce65baf1e3e1 Mon Sep 17 00:00:00 2001 From: Antoniu Miclaus Date: Fri, 19 Nov 2021 10:56:27 +0200 Subject: iio: expose shared parameter in IIO_ENUM_AVAILABLE The shared parameter should be configurable based on its usage, and not constrained to IIO_SHARED_BY_TYPE. This patch aims to improve the flexibility in using the IIO_ENUM_AVAILABLE define and avoid redefining custom iio enums that expose the shared parameter. An example is the ad5766.c driver where IIO_ENUM_AVAILABLE_SHARED was defined in order to achieve `shared` parameter customization. The current state of the IIO_ENUM_AVAILABLE implementation will imply similar redefinitions each time a driver will require access to the `shared` parameter. An example would be admv1013 driver which will require custom device attribute for the frequency translation modes: Quadrature I/Q mode and Intermediate Frequency mode.
