+What: /sys/class/leds/<led>/color/sync_enable
+Date: January 2019
+KernelVersion: 5.0
+Contact: Dan Murphy <dmurphy@ti.com>
+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 <dmurphy@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.
+
+What: /sys/class/leds/<led>/color/<led color>
+Date: January 2019
+KernelVersion: 5.0
+Contact: Dan Murphy <dmurphy@ti.com>
+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.
