Subject: [PATCH 5/6] ARM: dts: meson8b: odroidc1: add iio-hwmon for the chip temperature
Date: Sat, 12 Jan 2019 14:06:48 +0100 [thread overview]
Message-ID: <20190112130649.23838-6-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20190112130649.23838-1-martin.blumenstingl@googlemail.com>
SAR ADC enabled channel 8 can be used to measure the chip temperature.
This can be made available to the hwmon subsystem by using iio-hwmon.
