Subject: [PATCH 3/7] iio: adc: ad7091r: Move defines to header file
Date:   Tue, 21 Nov 2023 18:35:24 -0300
Message-ID: <8aa859817e86408733a81cf31b932f0efa273c71.1700595310.git.marcelo.schmitt1@gmail.com>

From: Marcelo Schmitt <marcelo.schmitt@analog.com>

Move AD7091R register, channel and event definitions to the header file
so other AD7091R device drivers may use those declaration in follow up
patches.
