Hi Shawn,
=== Device Tree ===
- Tested audio on imx51 babbage board with a full dt kernel, which means I got i2c, sgtl5000 codec, mc13892 regulator, ssi and sdma working on device tree.
Did you get the sgtl5000 to work out of the box? I'd think the cache handling
No. I started from a fixed version. It's one of the open issues I meant in my report. It's great to see you start submitting to shoot it. I will give it a test today.
For record, besides the above (solved now :), we have to address a number of issues to get the device tree audio ready for submitting.
* The dynamic device id in device tree makes the device matching using name in ASoC core even harder[1].
* The regulator binding for device tree is still missing. There is a post [2] from Zhuang Haojian. But it's pretty rough and still needs some work.
* There is an argument between merging imx-ssi into fsl-ssi (ssi driver on powerpc) and simply dding dt support for imx-ssi [3].
* We still have not reached an agreement on how to bind dma request line (not the physical channel) in device tree [4].
