No need for ack. The DTS have to go through arm-soc so I will pick it
up when dependencies get in and bindings are accepted (acked or
applied). We have now merge window so I guess this will go to v5.4-rc1
at earliest.

If you want to speed up things in future, be sure that dependencies
(headers) are applied as early as possible.

Best regards,
Krzysztof
