Subject: [PATCH v3 22/30] iio: adc: sun4i-gpadc-iio: add support for A83T thermal sensor
Date: Thu, 30 Aug 2018 17:45:10 +0200 [thread overview]
Message-ID: <20180830154518.29507-23-embed3d@gmail.com> (raw)
In-Reply-To: <20180830154518.29507-1-embed3d@gmail.com>
This patch adds support for the A83T ths sensor.
The A83T supports interrupts. The interrupt is configured to update the
the sensor values every second.
