+Contact:	Dan Murphy <dmurphy@ti.com>
+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 via the equation below:
+
+		led_brightness = requested_value * led_color_intensity/led_color_max_intensity
+
+		For additional details please refer to
+		Documentation/leds/leds-class-multicolor.rst.
+
+		The value of the color is from 0 to
+		/sys/class/leds/<led>/max_brightness.
+
+What:		/sys/class/leds/<led>/colors/<led_color>_intensity
+Date:		Sept 2019
+KernelVersion:	5.5
+Contact:	Dan Murphy <dmurphy@ti.com>
+Description:	read/write
+		The led_color directory is dynamically created based on the
+		colors defined by the registrar of the class.
+		The value for the led_color is defined in the
+		include/dt-bindings/leds/common.h. There is one directory per
+		color presented.  The intensity file is created under each
+		led_color directory and controls the individual LED color
+		setting.
+
+		The value of the color is from 0 to
+		/sys/class/leds/<led>/colors/<led_color>_max_intensity.
+
+What:		/sys/class/leds/<led>/colors/<led_color>_max_intensity
+Date:		Sept 2019
+KernelVersion:	5.5
+Contact:	Dan Murphy <dmurphy@ti.com>
+Description:	read only
+		Maximum intensity level for the LED color, default is
+		255 (LED_FULL).
+
+		If the LED does not support different intensity levels, this
+		should be 1.
