Hi Krzysztof,

I was waiting for your DT binding bifurcation patch to be merged before posting the next version, which is why I didn’t respond earlier. 
I had planned to include the hardware constraints explanation in the next commit message.

I’ll make sure to address all pending comments in the upcoming revision.

Thanks,
Ram.
