Subject: [PATCH 10/16] iio: adc: sun4i-gpadc-iio: add support for A83T thermal sensor
Date: Fri, 26 Jan 2018 16:19:35 +0100	[thread overview]
Message-ID: <20180126151941.12183-11-embed3d@gmail.com> (raw)
In-Reply-To: <20180126151941.12183-1-embed3d-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

This patch adds support for the A83T ths sensor.

The A83T does not support interrupts. This seems to be broken.
The calibration data is writen at the begin of the init process.

Signed-off-by: Philipp Rossak <embed3d-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>
