OK that makes sense.

So how about this:

- Have Long post a new version that splits out the creation of the new
  Kconfig symbol ARCH_AMBARELLA into it's own patch. I assume Arnd could
  provide an ACK on this?

- I create an immutable branch that contains that the two dt-binding
  patches, plus the ARCH_AMBARELLA Kconfig patch.

- Then I can merge the clk driver cleanly. The DTS folks can take the
  DTS changes.

If the DTS folks didn't want the ARCH_AMBARELLA in the immutable branch,
then we could do two immutable branches:
one for ARCH_AMBARELLA from SoC folks, and one from me for the
dt-bindings.

Alternatively, I could just provide an Acked-by for the clk driver, and
this could just go through the SoC tree.
