Subject: [PATCH v2 5/5] iio: adc: at91-sama5d2_adc: use max sample rate
Date: Wed, 11 Oct 2017 09:35:32 +0300 [thread overview]
Message-ID: <1507703732-29175-6-git-send-email-eugen.hristev@microchip.com> (raw)
In-Reply-To: <1507703732-29175-1-git-send-email-eugen.hristev@microchip.com>
Change driver settings to use maximum sample rate clock.
This is useful to achieve best possible sampling rate
if we use DMA.
