Subject: [PATCH v1 1/1] iio: frequency: adf4350: Make use of device properties
Date: Wed,  2 Feb 2022 22:29:36 +0200	[thread overview]
Message-ID: <20220202202936.56475-1-andriy.shevchenko@linux.intel.com> (raw)

Convert the module to be property provider agnostic and allow
it to be used on non-OF platforms.
