Is this really correct? The Datasheet specificies 26MHz, some boards
have 27Mhz, but 33?

This node is not necessary. The watchdog is enabled already in the dtsi
file.

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.

Yes, you're right, I'll send a v2 of this patch without the watchdog.

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.
