└─>LED support for Renesas TPU
In linux kernel since version 3.1 (release Date: 2011-10-24)  
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.
