Hi Colin,
Please consider pulling TrimSlice updates for 2.6.40 merge window.
These patches add registration of i2c, audio and USB devices.

Mike, a comment and a question:

First off, your git branch isn't based on tegra's for-next branch, but
rather something much in the future of it. Hence, the merge brings in a
bunch of unrelated changes. It is a fast-forward though so it's
probably fine?

 
My branch is based on recent Linus' tree. I presume Colin will reabse
his -next on it before sending pull request...

Second, I tried to test this, but failed. I hit two issues:

1) USB didn't seem to work for me; the following prints continuously:

[   93.952248] usb 3-1: new high speed USB device number 126 using tegra-ehci
[   94.022291] hub 3-0:1.0: unable to enumerate USB device on port 1

This means I can't use the built-in SSD as the root filesystem.

I see this problem irrespective of whether I tell U-Boot to initialize
USB before booting or not.

Yeah, this is caused by issue with USB1 port reset. Greg already took
the patch that fixes it (1).

Which branches did you have merged to test this? I did:

* Create a new branch from Tegra's for-next.
* Merge the branch from your pull request.
* Merge ASoC for-2.6.40 branch to pick up the audio driver.
* Cherry-pick a few I2C fixes I've been working on. I don't recall if
they are necessary for Trimslice or not, but shouldn't hurt.

I'd rather take the ASoC for-2.6.40 and apply the first two patches +
I2C fixes.

2) I can boot into a recent ChromeOS filesystem on the SD card, and
see e.g. the audio driver initialize OK. However, both speaker-test
and aplay segfault immediately. They work fine on other HW, such as
Seaboard, with this disk image. I know this used to work on Trimslice
a few weeks back, so perhaps I'll go and try an older disk image.

I've never tried audio with ChromiumOS. I've tested with Maverick and
aplay didn't complain.
