Is this really correct? The Datasheet specificies 26MHz, some boards have 27Mhz, but 33?The clock value on this board is? 32.768kHz, so 32768 * 1024. I've tried others value, all others produce weird behaviour on the serial.
Ok, so your board runs with the 32.768KHz clock input. I didn't know there are boards that use this as the reference clock. It seems this is not handled in the current clk code. Could you test the patch I just sent to the mailing list (Cced you) and provide a Tested-by tag if it works? The clock frequency provided in the device tree shouldn't make a difference then anymore. You should specify it to 0 if you have nothing connected there.
