What happened here? This was not present before. Drop description.
I will delete this description in patch v5

Reset pin of aw883xx chip
The same case. Drop description.
I commented only for irq-gpios that they need description.
I will delete this description in patch v5

- sound-channel:
- description:
Number of sound channels of the aw883xx chip
Your description does not explain me much. Number of supported sound channels is usually fixed in the hardware, thus coming from compatible. Therefore this might mean something else... but anyway your driver does not use it really, so just drop it.
I will delete this property node in patch v5
Thank you very much for your advice
