+	  This option enables build of the LED TPU platform driver,
+	  suitable to drive any TPU channel on newer Renesas SoCs.
+	  The driver controls the GPIO pin connected to the LED via
+	  the GPIO framework and expects the LED to be connected to
+	  a pin that can be driven in both GPIO mode and using TPU
+	  pin function. The latter to support brightness control.
+	  Brightness control is supported but hardware blinking is not.
