A list of special device files (2.4 / 2.6 kernel only!)
The 2.4/2.6 kernels expose some old-style /proc interfaces
- /proc/jz/numlock_led - write 0 or 1 to the LED
- /proc/jz/capslock_led - write 0 or 1 to the LED
- /proc/jz/eth0_led - write 0 or 1 to the LED
- /proc/jz/battery - reads battery flag
- /proc/jz/battery-level - reads battery status
- /proc/jz/wifi-power - write 0 or 1 to power up WiFi
/proc/jz/backlight - write value to backlight PWM (0..300)
/proc/powerdown
Touch screen position

This all will be replaced by modern API in the Letux-kernels >4.13
