- help
- 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.
