          cannot be used. This driver supports hardware blinking with an on+off
          period from 62ms to 125s. Say Y to enable LEDs on the HP iPAQ hx4700.

+         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.
