+Description:	read/write
+		Writing a 1 to this file will enable the synchronization of all
+		the defined color LEDs within the LED node.  Brightness values
+		for each LED will be stored and written when sync is set to 1.
+		Writing a 0 to this file will disable syncing and allow

+Description:	write only
+		Writing a 1 to this file while sync_enable is set to 1 will
+		write the current brightness values to all defined LEDs within
+		the LED node.  All LEDs defined will be configured based
+		on the brightness that has been requested.
+

+Description:	read/write
+		The led_color directory is dynamically created based on the
+		colors defined by the registrar of the class.
+		The led_color can be but not limited to red, green, blue,
+		white, amber, yellow and violet.  Drivers can also declare a
+		LED color for presentation.  There is one directory per color
+		presented.  The brightness file is created under each
+		led_color directory and controls the individual LED color
+		setting.
+
+		If sync is enabled then	writing the brightness value of the LED
+		is deferred until a 1 is written to
+		/sys/class/leds/<led>/color/sync.  If syncing is
+		disabled then the LED brightness value will be written
+		immediately to the LED driver.
+
+		The value of the color is from 0 to
+		/sys/class/leds/<led>/colors/<led_color>/max_brightness.

+Description:	read only
+		Maximum brightness level for the LED color, default is
+		255 (LED_FULL).
+
+		If the LED does not support different brightness levels, this
+		should be 1.
