This review is part of a sequence that update ChromeOS to the latest upstream
Tegra ASoC driver, and add support for Seaboard to that driver.

The reviews need to be merged in the following order:
 
http://codereview.chromium.org/6577007
http://codereview.chromium.org/6579016
http://codereview.chromium.org/6580011
http://codereview.chromium.org/6579017
http://codereview.chromium.org/6574010
http://codereview.chromium.org/6577008
http://codereview.chromium.org/6576013

I tested:
* Audio playback on Harmony (headphone jack)
* Audio capture on Harmony (mic jack)
* Audio playback on Seaboard (headphone portion of headset jack)
* Audio capture on Seaboard (mic portion of headset jack)

Note: The existing ASoC machine driver in ChromeOS hacks a number of WM8903
codec registers directly in order to configure capture. This driver does not do
this. In order to record correctly, you will need to run alsamixer, and adjust a
few controls from their default:

Harmony:
Unmute "Left Input PGA"
Raise Level of "Left Input PGA" e.g. to max
Set "Right Capture Mux" to "Left"

(Ventana would be identical to Harmony, except this patchset doesn't set up the
required platform data for Ventana)

Seaboard:
Unmute "Right Input PGA"
Raise Level of "Right Input PGA" e.g. to max
Set "Left Capture Mux" to "Right"

Other platforms are not currently supported, since I haven't written ASoC
machine drivers that support their audio configuration yet. I'll look at the
schematics for other boards next. It's possible that one of the existing Harmony
or Seaboard machine drivers will be suitable for the other platforms already.

Ping. I'd like to base my Audio-over-HDMI support on this patchset. HDMI support
is due in codereview this Friday. If I base my changes on the current audio
driver, there will be a merge conflict between this set of patches and the HDMI
audio support. Thanks.

Olof should probably be the one to review these changes as I haven't been
working in the kernel for a while now.  Olof, does that sound right to you?

Thanks,
    Anton

Yeah, I've been processing this one on spare cycles. The base import
is massive and it kicked off some thought trains about if we can
handle these kind of massive backports in a better way, since they're
getting to be big (not just audio, wifi is doing a bunch of them too).


I don't have any issues with the patch set per se yet. I'll take a
closer look today.

Thanks for your patience with these, Stephen.

Doing a full-system backport like this isn't ideal, but it's the best we have
for now. Doing the series of cherry-picks would be too invasive, and the actual
driver patches depend a fair amount of other asoc updates. So for this time
around I'm OK with it.

I couldn't actually download this patch due to Rietveld limitations, but thanks
to the excellent description I could just reproduce it instead. As a side
effect, I ended up with a slightly newer version (synced at
1d471cd1261a44a3b28350bef7e5113a4609c106).

Will push shortly once I have seen it work on Seaboard here.
