- * TSL2563 light sensor functional test
- *
- * When I spoof an I2C device on i2c adapter 0, I see these files show
- * up in /sys/devices/pci0000:00/0000:00:02.0/i2c-0/0-0029/iio/device0:
- *  -r--r--r-- 1 root root 4096 Mar 25 17:21 adc0
- *  -r--r--r-- 1 root root 4096 Mar 25 17:21 adc1
- *  -rw-r--r-- 1 root root 4096 Mar 25 17:21 calib0
- *  -rw-r--r-- 1 root root 4096 Mar 25 17:21 calib1
- *  lrwxrwxrwx 1 root root    0 Mar 25 17:21 device -> ../../../0-0029
- *  -r--r--r-- 1 root root 4096 Mar 25 17:21 lux
- *  drwxr-xr-x 2 root root    0 Mar 25 17:21 power
- *  lrwxrwxrwx 1 root root    0 Mar 25 17:21 subsystem -> ../../../../../../../class/iio
- *  -rw-r--r-- 1 root root 4096 Mar 25 17:21 uevent
- * This is done with:
- *   echo tsl2563 0x29 > /sys/class/i2c-adapter/i2c-0/new_device
- *
- * Raw and calibrated ADC data come from adc{0|1} and calib{0|1}, but
- * it is probably best to use the lux file because it gives the calibrated
- * ADC translated to luminescence.
