Hi Feng,
I've had a look at your patches. I went with the patches at
git.linaro.org and diffed them against master, this was to avoid
commenting on the things you already fixed.
See comments below for details. In general I've mostly looked at the
integration, rather than the alsa-ucm.c file. I think the integration is
well done, and I think we should merge this sooner rather than later.
The nitpicks below should not block merging (possibly with the exception
of the public API question I have about proplist.h).
My biggest question is therefore about the future. I just found out that
the Linaro Multimedia working group is dismantling, and as none of our
core team really know this stuff by heart, who will be around to
maintain this code? If we want to refactor things later on, who can test
that we don't break UCM in some way?

Nitpick: I don't think we need setup_mixer_ucm. Just call
sink_set_port_ucm_cb or pa_alsa_ucm_set_port instead.

Hmm, this is probably not your fault, but for being a public header file
use-case.h is probably not the best name - either <asound/use-case.h> or
<asound-use-case.h> would have been better, but I guess there's nothing
to do about that. (But do you really need both for just the
snd_use_case_mgr_t symbol?)

We already have "enum pa_device_type", "enum pa_direction" and "enum
pa_stream_direction" (see pulse/def.h), any chance we can use one of
those instead of adding yet another enum meaning the same thing?

You don't need this struct pa_alsa_port_data_ucm. Just specify 0 in the
call to pa_device_port_new.

pdevices is not used on any of the "root" calls to
pa_alsa_ucm_add_ports_combination. It would be more elegant to add a
simple wrapper around pa_alsa_ucm_add_ports_combination that would
remove pdevices (and dev_num?) parameters from the call here.
