Subject: [PATCH 027/146] iio: adc: sun4i-gpadc-iio: add support for H5 thermal

sensor

This patch adds support for the H5 ths sensor.
|
|
|
|
The H5 supports interrupts. The interrupt is configured to update
|
|
the sensor values every second. The sensor is except the scale/offset
|
|
values and an additional sensor for the gpu the same. A temperatur higer
|
|
than 70°C needs an other formula. Since the operating temperatures maximum
|
|
is 70°C this case was neglegted.
