44 Multicolor Class Brightness Control
46 The brightness level for each LED is calculated based on the color LED
48 the requested brightness.
50 ``led_brightness = brightness * multi_intensity/max_brightness``
53 A user first writes the multi_intensity file with the brightness levels
76 The user can control the brightness of that multicolor LED group by writing the
77 global 'brightness' control.  Assuming a max_brightness of 255 the user
79 128 to the global brightness file then the values written to each LED will be
86     # echo 128 > /sys/class/leds/multicolor:status/brightness
98 Reading the global brightness file will return the current brightness value of
103     # cat /sys/class/leds/multicolor:status/brightness
