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. Brian
