This should be implemented using gpiolib - see WM8962 for an example of this. That way the control can be plugged into more other subsystems in the kernel (probably including whenever I or someone else gets around to it a widget like the one you open code in a later patch). I know some of the drivers do export the GPIOs using custom APIs but that's something that should be fixed.
Also, fix platform_data handling to have an explicit "don't touch this pin" option.
This should've been a separate patch since it's OK to go in as-is.
Temporarily hack out the mic detection platform_data handling for simplicity
There's no patch restoring the functionality...
tesing the GPIO changes. Should the write-sequencer enabling be conditional?
Yes. It's not actually enabling the write sequencer itself, it's enabling a low rate clock that's shared between a number of functions in the device including jack detection. Without the clock jack detection will not function.
