Subject: [PATCH v7 4/6] iio: adc: meson: add enum for iio channel numbers
Date: Fri, 14 Jul 2023 14:37:51 +0300	[thread overview]
Message-ID: <20230714114010.293440-5-gnstark@sberdevices.ru> (raw)
In-Reply-To: <20230714114010.293440-1-gnstark@sberdevices.ru>

Channels could be referenced in the driver code and using enum allows
to make it more robust.
