How to Read SAR ADC Values on AML-S905X-CC

There are 2 SAR ADC inputs reading up to 1.8V on the 2J8 header behind the HDMI port. The SAR ADC values can be found in the following files: cat /sys/bus/iio/devices/iio:device0/in_voltage0_raw cat /sys/bus/iio/devices/iio:device0/in_voltage2_raw They can be used for keypads, temperature sensing, and more but make sure to not exceed 1.8V.
