  Add an example on enabling of USB offload for the Q6DSP.  The routing can
be done by the mixer, which can pass the multimedia stream to the USB
backend.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:

dtschema/dtc warnings/errors:

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20231011002146.1821-26-quic_wcheng@quicinc.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

Would you happen to know what the error is in this case?  I made sure I 
was running the latest dtschema (v2023.9) and had yamllint installed as 
well.  When I took a look at the DTB and DTS output it looked ok...

             usb-dai-link {
                 link-name = "USB Playback";
                 cpu {
                     sound-dai = <&q6afedai USB_RX>;//--->syntax error?
                 };

                 codec {
                     sound-dai = <&usbdai USB_RX>;
                 };

                 platform {
                     sound-dai = <&q6routing>;
                 };
             };

I didn't make any changes to this in between v7 and v8, but v7 passed:
