Is this really an LED, or just a generic output?

Indent with tabs, please.

Does this drive an LED or control a fan? If it controls a fan, it should use the
gpio-fan binding, and not pretend to be an LED.

It also does not validate against the gpio-leds binding:

sun8i-r16-renew-vista-e.dtb: leds: 'fans-on', 'pad-intz' do not match any of the
regexes: '(^led-[0-9a-f]$|led)', 'pinctrl-[0-9]+'

Please use "DACL" and "DACR" here, instead of the AIF1 Slot 0 widgets. The AIF1
Slot 0 widgets do not accurately describe the audio routing and are only kept
for backward compatibility.

You enable drivevbus and label it as "usb0-vbus". But this suggests the VBUS is
always on. Which is correct?
