+
+/sys/class/leds/<led>/hw_pattern
+--------------------------------
+
+Specify a hardware pattern for the ST1202 LED. The LED
+controller implements 12 low-side current generators
+with independent dimming control. Internal volatile memory
+allows the user to store up to 8 different patterns.
+Each pattern is a particular output configuration in terms
+of PWM duty-cycle and duration (ms).
+
+To be compatible with the hardware pattern
+format, maximum 8 tuples of brightness (PWM) and duration must
+be written to hw_pattern.
+
+- Min pattern duration: 22 ms
+- Max pattern duration: 5660 ms
+
+The format of the hardware pattern values should be:
+"brightness duration brightness duration ..."
+
+/sys/class/leds/<led>/repeat
+----------------------------
+
+Specify a pattern repeat number, which is common for all channels.
+Default is 1; negative numbers and 0 are invalid.
+
+This file will always return the originally written repeat number.
+
+When the 255 value is written to it, all patterns will repeat
+indefinitely.
