Perhaps merging this was a bit premature. I just gave it a spin, but
this is apparently not even expected to work without various changes
that are still work in progress. For example, the codecs fails to probe
with:

[   11.077727] qcom-prm gprsvc:service:2:2: DSP returned error[100100f] 1
[   11.077926] rx_macro: probe of 3200000.rxmacro failed with error -22

and you need an out-of-tree hack to get around that:

	https://git.linaro.org/people/srinivas.kandagatla/linux.git/commit/?h=lenovo-x13s-6.1.0-rc7-audio&id=0bffb619bf7929c56b7458af3a583fa9ce87fc26

I learned that the hard way after a debugging session.

Even with those hacks in place, I see:

[   14.466733] qcom-soundwire 3330000.soundwire-controller: qcom_swrm_irq_handler: SWR bus clsh detected
[   14.522324] qcom-soundwire 3330000.soundwire-controller: swrm_wait_for_frame_gen_enabled: link status not disconnected
[   14.522372] qcom-soundwire 3330000.soundwire-controller: link failed to connect

so this does not look like it was ready to be merged. I'm still not sure
what else is needed, but there are a bunch of other work-in-progress
changes in the above branch.

Srini, next time can you please document such dependencies in the cover
letter to avoid having people debug things that are not even supposed to
work yet and so that we can hold-off on merging the dts changes until
driver support in place.
