 427          This option enables support for the LEDs on the HTC ASIC3. The HTC
 428          ASIC3 LED GPIOs are inputs, not outputs, thus the leds-gpio driver
 429          cannot be used. This driver supports hardware blinking with an on+off
 430          period from 62ms to 125s. Say Y to enable LEDs on the HP iPAQ hx4700.

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