-sysfs contains a selftest entry. It measures each channel
-voltage level and checks if it looks reasonable. If the level is too high,
-the led is missing; if the level is too low, there is a short circuit.
+LP5523 has the internal program memory for running various LED patterns.
+For the details, please refer to 'firmware' section in leds-lp55xx.txt
Selftest uses always the current from the platform data.
