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
9                 equation below:
10
11                 led_brightness = brightness * multi_intensity/max_brightness
12
13                 For additional details please refer to
14                 Documentation/leds/leds-class-multicolor.rst.
15
16                 The value of the LED is from 0 to
17                 /sys/class/leds/<led>/max_brightness.

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.
