Ok, thanks for the info.

I plan to just pick up the reset DT binding documentation patch (1/5)
and the reset driver patch (2/5) then, whether they are sent separately
or as part of the larger remoteproc series does not matter to me.

The dtsi patch would have to go through the arm/qualcomm tree.
I can put the reset patches onto a separate branch that could be pulled
into the qcom tree ahead of the dtsi change, or you could send the dtsi
change with numbers at first, and only replace them with the header
defines after patch 1 is merged through the reset tree.
