+What:          /sys/class/leds/<led>/color/sync_enable

+Description:   read/write
+               Writing a 1 to this file will enable the sychronization of all
+               the defined color LEDs within the LED node.  Writing a 0 to
+               this file will disable syncing.

+What:          /sys/class/leds/<led>/color/sync
+Date:          January 2019
+KernelVersion: 5.0
+Contact:       Dan Murphy <dmur...@ti.com>
+Description:   write only
+               Writing a 1 to this file while sync_enable is set to 1 will
+               synchronize all defined LEDs within the LED node.  All LEDs
+               defined will be configured based on the brightness that has
+               been requested.
+
+               If sync_enable is set to 0 then writing a 1 to sync has no
+               affect on the LEDs.

+Description:   read/write
+               These files are dynamically created based on the colors defined
+               by the registrar of the class.
+               The led color(s) can be but not limited to red, green, blue,
+               white, amber and violet.  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>/max_brightness.
