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

| Description: read |
| The multi_index array, when read, will output the LED colors |
| as an array of strings as they are indexed in the |
| multi_intensity file. |

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