The driver is used for rockchip board using a rt5650/rt5645. Test on RK3288 with rt5650.
Similar comments to the Maxim driver plus...

Don't do this - if the functionality isn't there in the CODEC driver get it implemented before you use it. Make sure you're using the API the CODEC actually ends up exporting.

No, don't do this - as discussed in another Chromebook review (I'm guessing this is a Chromebook) the jacks should represent the physical jacks in the system. It's possible you have separate headphone and microphone jacks but I really expect microphone and button to be on the same socket.
