Ok, understood. I will go through each one of the CCM registers and check what clocks can be turned off. This may take some time though as it needs proper testing. I suggest that we keep the current clock settings as is, so that the board support can reach U-boot, then later I can submit a patch for turning off the unneeded clocks.
