Here you're also missing important changes from the tree I told you to use.
These should be GPIO_ACTIVE_HIGH otherwise the LEDs will be on when they should
be off.

You've also added this line which results in an error like this:

  pinctrl-th1520 fffff4a000.pinctrl: pin AUDIO_PA8 already requested
by leds; cannot claim for fffff52000.gpio:536

Did you run this on your BeagleV Ahead?
