Hi! Currently there is no way for userspace to make any configuration of the VCNL4040 sensors, but only the sensor readings are exported in sysfs. To support basic control of the sensors such as enable/disable and setting integration time value, sysfs attributes for this needs to be exported. To begin with the runtime power management turns both sensors (ALS, and PS) on before reading the sensor register values and then switching them off again. But when doing so it writes the whole register instead of just switching the power on/off bit. This needs to be fixed in order to make other persistent configurations.
