Subject: [PATCH 5/6] iio/adc: ingenic: modify
Date: Wed, 21 Jul 2021 12:53:16 +0200	[thread overview]
Message-ID: <20210721105317.36742-6-cbranchereau@gmail.com> (raw)
In-Reply-To: <20210721105317.36742-1-cbranchereau@gmail.com>

The current code does not allow to set MD to 0 to sample AUX0, fix it for the JZ4760(B).
