Dez/2006

The driver is modified now.
Please use the driver in the new-folder.


13/Nov/2006

This is a working version of a driver for 10 LED and up to 8 GPIO.
The 8 GPIO is only vailable on the BGA-Chip-Version.

With this driver you can use all pins as input and output and the LED in
all modes for the ethernet-port, see datasheet.
The driver is based on the version from Sergio Aguayo with any corrections for
the LED-support.
The driver is not compatible with the old driver !
With the tool "admgpioconfig" you can set the pins to input or output.
With sending "led switch x y" (x = LED, y = mode) to the 
/dev/gpioX (8..17) you can set all other modes if the pin set to output
first.
By reading from /dev/gpioX you receive the mode you have set in output-mode
or the input-state 0/1 in input-mode.
The blink-modus on LED is only the hardware-led-flash-mode.
You must modify your start-scipts to set up the dev-entries like:
for i in 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 do; mknod /dev/gpio$i c167 $i; done
No /dev/ledX is supported.

---------------------------------------------------------------------------
Please not ! if you remove the LEDs from the borad in input mode you have 
open CMOS pins ! No pullup or pulldown resistor are vailable. Open CMOS 
pins are highly sensitiv for static voltage ! You can damage your device !
---------------------------------------------------------------------------

The driver is alpha, the logic of the code is not consistent. So i will
rewrite the code to differentiate "mode" and "value"  and support all 15 LED.

For compiling your kernel with this version you have to copy the
led_new.c/led_new.h as led.c/led.h to your kernel folder 
linux/arch/mips/am5120/.
Or with the kamikaze from http://midge.vlad.org.ua you can use the 2 patches 
202-... and 203-... .
( if you only use the 202-... patch you have 15 LED for output only,
compatible with the original)
