Hello,
Dmitry,
I forgot to modify the binding to declare the new compatible "gt9147".
Rob,
can I modify the binding without converting it first to yaml?

Best regards

Yannick Fertré

If it is compatible with gt912 then the driver does not need another compatible in the code I think. Rob will tell more.
