| The ISL29003 is an integrated light sensor with a 16-bit integrating type |
| ADC, I2C user programmable lux range select for optimized counts/lux, and |
| I2C multi-function control and monitoring capabilities. The internal ADC |
| provides 16-bit resolution while rejecting 50Hz and 60Hz flicker caused by |
| artificial light sources. |
| The driver allows to set the lux range, the bit resolution, the operational |
| mode (see below) and the power state of device and can read the current lux |
| The ISL29003 does not have an ID register which could be used to identify |
| it, so the detection routine will just try to read from the configured I2C |
| address and consider the device to be present as soon as it ACKs the |
| 0: 0 lux to 1000 lux (default) |
| 0: diode1's current (unsigned 16bit) (default) |
| 1: diode1's current (unsigned 16bit) |
| 2: difference between diodes (l1 - l2, signed 15bit) |
| 0: device is disabled (default) |
| returns the value from the last sensor reading |
