The sleep indicator LEDs can be enabled/disabled by toggling GPIO162. Use the LED GPIO class to export this LED functionality to userspace. To enable: # echo 1 > /sys/class/leds/sleep_ind/brightness To disable: # echo 0 > /sys/class/leds/sleep_ind/brightness Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
