I have quickly hacked something based on what you had done for pcm037 with the MC13783 codec in some of your first sound patches. I know that this is not ready for mainline and I'm still struggling to debug my code, but I would like to have results quite soon so that my colleague could see what sounds (especially regarding to the volume) our system is capable to produce.
If you're struggling to find time to do full support for the CODEC a good technique is often to get just very basic fixed function support (say just DAC to headphone support) implemented and merged, then go back and implement
I'd also suggest looking at the current Freescale BSPs - obviously this device is used on a lot of Freescale reference boards and I believe there's a reasonably mainlineish driver in the BSPs they have for current devices.

I think they dropped support for the MC13783 in their BSPs. The MC13783 code is still contained in sound/arm/mxc-alsa-pmic.c and a 200k file drivers/mxc/pmic/mc13783/pmic_audio.c. That's not exactly mainlineish...
