This probably qualifies for self review, but it wasn't 100% clear to me
(since we're not supporting all of the chip features), so I'm submitting
as a fast track, on my own behalf.

4. Technical Description
Requested Binding: Minor
This project proposes to deliver a device driver for the
CMedia CMI8738 family of audio devices. These parts are found
in discrete audio boards, and on some motherboards. The family
consists of the CMI8738, CMI8768, and CMI8338. (There are submodels
in the family as well.) The parts are somewhat older, and are not
AC'97 compliant, but some of them do have support for some features such
as 5.1 or 7.1 surround sound.
The driver would be called "audiocmi", and would be delivered in a package
SUNWaudiocmi. It would use the Consolidation Private Boomer (PSARC 2008/318)
interfaces.
The package name SUNWaudiocmi would "Committed", and the "audiocmi" driver
would be "Uncommitted", as would any specific features delivered by
the audiocmi driver.
We are not planning on providing FMA support for this driver (we don't
believe it is strategic, and no other audio drivers have FMA support
currently).
In initial delivery, we are only planning on supporting basic stereo playback
and record using the analog ports on the device. However, architecturally,
we'd like to allow for the chance to broaden this support for surround sound
or SPDIF audio in the future, if demand presents itself. (We would treat
such features as an RFE for the future.)
