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.

In order get the clock by phandle and use it with regmap it needs to be compatible with syscon. The DMC driver uses two registers from clock register set and needs the regmap of them.
