5 Description: read/write
6 Writing to this file will update all LEDs within the group to a
7 calculated percentage of what each color LED intensity is set
8 to. The percentage is calculated for each grouped LED via the
11 led_brightness = brightness * multi_intensity/max_brightness
13 For additional details please refer to
14 Documentation/leds/leds-class-multicolor.rst.
16 The value of the LED is from 0 to
17 /sys/class/leds/<led>/max_brightness.

32 Description: read/write
33 This file contains array of integers. Order of components is
34 described by the multi_index array. The maximum intensity should
35 not exceed /sys/class/leds/<led>/max_brightness.
