^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) 1. Overview
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) ===========
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) The driver is intended to work on both low-end (EP9301, EP9302) devices with
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) 5-channel ADC and high-end (EP9307, EP9312, EP9315) devices with 10-channel
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) touchscreen/ADC module.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) 2. Channel numbering
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) ====================
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) Numbering scheme for channels 0..4 is defined in EP9301 and EP9302 datasheets.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) EP9307, EP9312 and EP9312 have 3 channels more (total 8), but the numbering is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) not defined. So the last three are numbered randomly, let's say.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) Assuming ep93xx_adc is IIO device0, you'd find the following entries under
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) /sys/bus/iio/devices/iio:device0/:
