Subject: [RFC PATCH 2/7] iio: adc: axp20x-adc: allow to skip ADC rate setup now
Date: Wed, 20 Sep 2017 23:18:09 +0800	[thread overview]
Message-ID: <20170920151814.22461-3-icenowy@aosc.io> (raw)
In-Reply-To: <20170920151814.22461-1-icenowy@aosc.io>

The ADC rate setup on AXP803 is more complex than AXP20x/22x.

As it's not a necessary setup, allow it to be skipped, to allow simpler
AXP803 support now.
