Beaglebone black build kernel

Hello.
I have faced with problem (or task). I have Beaglebone black and my own cape with TLV320AIC3102 codec. Cape has Line OUT and Mic IN jacks. Now I need to build kernel with tlv320aic31xx driver (Because tlv320aic3x driver doesn’t work with MIC1 and MIC2). Master branch of linux kernel has source of tlv320aic31xx driver. I built several kernels (Robert Nelson, eLinux) but this kernels didn’t have this driver (it had only tlv320aic3x). When script builds kernel it changes git branch of linux kernel source. And I doesn’t see tlv320aic31xx.c in the new branch. Could you give me direct how I can add this driver to my kernel build.

Umm, cherry pick the commits and apply to the default tree..

Robert, thank you for your advice.
Unfortunately I don’t have enough experience in kernel building. But I want to build it ))
Your script do steps (in general):
1 Switch to branch (for example 3.8)
2 Download linux kernel sources
3 path kernel
4 build kernel
… other steps

And now should I “cherry-pick” the commits manualy or should I overwrite building script(s)?
I will appreciate very much for you if you can find a little time to answer my question.

Best regards,
Yurii

Thank you.
I’m a little confused. I think I should do “cherry-pick” on the git_kernel () stage (git.sh) Is it correct?
P.S.: Sorry for the stupid questions. It is still hard for me.

Best regards,
Yurii
