* Add a generic LED driver for flashing lamps.Poul-Henning Kamp2003-11-032-0/+279
The hardware driver decides the name under /dev/led and provides the function to turn the lamp on/off. All leds are serviced by a single timeout which runs at a basic rate of hz/10. The LED is controlled by ascii strings as follows. 0 Turn off. 1 Turn on. f Flash: _- f2 Flash: __-- f3 Flash: ___--- f4...f9 etc. d%d Digits.
