I'm working on a custom board based on i.MX25 PDK. All devices in my board are working with kernel 3.2.60 except audio, because this kernel doesn't have support for the SGTL5000. I don't use device tree, all my hardware configuration is in the board file.
Now, I am trying to use device tree with a superior kernel version (3.14.12) to have the audio codec working, but I'm having a lot of problems with that. So my question is if it possible to give support for the audio codec in the board file with kernel 3.14.12, without using device tree, and in that case, how would I do it.
