As I said I need to take a look at CCF to see if it already there. If it is clock driver + mapping + patch for wl12xx should fix the issue you are facing. > Let me know if you need more info. BTW: have you happened to ubdate u-boot recently? There is a nice easter egg added there: f3f98bb ARM: OMAP4/5: Do not configure non essential pads, clocks, dplls. Which means that _essential_ clocks and pads are no longer configured. -- Péter
