1==============================2Cirrus Logic EP93xx ADC driver3==============================4 51. Overview6===========7 8The driver is intended to work on both low-end (EP9301, EP9302) devices with95-channel ADC and high-end (EP9307, EP9312, EP9315) devices with 10-channel10touchscreen/ADC module.11 122. Channel numbering13====================14 15Numbering scheme for channels 0..4 is defined in EP9301 and EP9302 datasheets.16EP9307, EP9312 and EP9315 have 3 channels more (total 8), but the numbering is17not defined. So the last three are numbered randomly, let's say.18 19Assuming ep93xx_adc is IIO device0, you'd find the following entries under20/sys/bus/iio/devices/iio:device0/:21 22 +-----------------+---------------+23 | sysfs entry | ball/pin name |24 +=================+===============+25 | in_voltage0_raw | YM |26 +-----------------+---------------+27 | in_voltage1_raw | SXP |28 +-----------------+---------------+29 | in_voltage2_raw | SXM |30 +-----------------+---------------+31 | in_voltage3_raw | SYP |32 +-----------------+---------------+33 | in_voltage4_raw | SYM |34 +-----------------+---------------+35 | in_voltage5_raw | XP |36 +-----------------+---------------+37 | in_voltage6_raw | XM |38 +-----------------+---------------+39 | in_voltage7_raw | YP |40 +-----------------+---------------+41
