Hi, I see that all your patches are part of 3.12-rc5 kernel.
Now I tested this example led program:
# Clearing LED-state to be sure
echo "disabled" > /sys/class/i2c-adapter/i2c-2/2-0032/engine1_mode
echo "disabled" > /sys/class/i2c-adapter/i2c-2/2-0032/engine2_mode
echo 0 > /sys/class/leds/lp5523:r/brightness
echo 0 > /sys/class/leds/lp5523:g/brightness
echo 0 > /sys/class/leds/lp5523:b/brightness
# Setting yellow light pattern and running it
echo "load" > /sys/class/i2c-adapter/i2c-2/2-0032/engine1_mode
echo "000001100" > /sys/class/i2c-adapter/i2c-2/2-0032/engine1_leds
echo "9d804000427f0d7f7f007f0042000000" >
/sys/class/i2c-adapter/i2c-2/2-0032/engine1_load
echo "load" > /sys/class/i2c-adapter/i2c-2/2-0032/engine2_mode
echo "000000000" > /sys/class/i2c-adapter/i2c-2/2-0032/engine2_leds
echo "9d800000" > /sys/class/i2c-adapter/i2c-2/2-0032/engine2_load
echo "run" > /sys/class/i2c-adapter/i2c-2/2-0032/engine2_mode
echo "run" > /sys/class/i2c-adapter/i2c-2/2-0032/engine1_mode
echo 20 > /sys/class/leds/lp5523:r/led_current
echo 2 > /sys/class/leds/lp5523:g/led_current
echo 0 > /sys/class/leds/lp5523:b/led_current
All sysfs entries exists and every echo returned 0.
But led does not start blinking that yellow ligh pattern.
So it not working on 3.12-rc5 kernel :-(
