No. For such patch ABI break is also not allowed in that case. Just
make the driver backwards compatible and both problems - non
bisectability and ABI break - go away.

One more point that I am not very clear about "non bisectability and
ABI break "

ABI, I suppose you mean dt-binding, right?
The I2C bindings and dts update will go through different tree, I
think. So dtbs_check may fail considering the PR merge order.

ABI break means breaking Application Binary Interface, so out of tree DTS
conforming to old bindings stop working with new kernel.

ABI is described by bindings and implemented by driver. You broke it in the
driver.

Thanks for your explanation. V2 will take care of this.

Thanks,
Peng.

Best regards,
Krzysztof
