Is it not possible to extend simple card to handle your use cases?
Given the very generic naming and the fact that things like jack
detection and so on should depend on the CODEC and board usually rather
than on the SoC it doesn't sound like this is Rockchip specific.

This also looks like you're reimplementing some device model enumeration
stuff which probably shouldn't be happening but let's understand the
problem you're trying to solve here before going too far into the code.
