I don't understand how that changes anything, these are all out of tree drivers based on an old kernel. I know that there are drivers for a lot of the peripherals that are in-use in the vendor tree etc. What I am looking to happen, before I apply patches for the k230, is that the clock dt-bindings will have landed in linux-next - and ideally the pinctrl ones too.
