Furthermore, it supports 8-bit\n+brightness control for each channel. This LED is typically used as a status\n+indicator in mobile devices. It also supports various parameters for hardware\n+patterns.\n+\n+The hardware pattern can be programmed using the \"pattern\" trigger, using the\n+hw_pattern attribute.\n+\n+/sys/class/leds/<led>/repeat\n+----------------------------\n+\n+The hardware supports only indefinitely repeating patterns. The repeat\n+attribute must be set to -1 for hardware patterns to function.\n+\n+/sys/class/leds/<led>/hw_pattern\n+--------------------------------\n+\n+Specify a hardware pattern for the RGB LEDs.\n+\n+The pattern is a series of brightness levels and durations in milliseconds.\n+There should be only one non-zero brightness level. Unlike the results\n+described in leds-trigger-pattern, the transitions between on and off states\n+are smoothed out by the hardware.\n+\n+Simple pattern::\n+\n+ \"255 3000 0 1000\"\n+\n+ 255 -+ ''''''-. .-'''''''-.\n+ | '. .'
