I have included rese-gpio removal here since it logically can be grouper with other manipulations with the bt/wifi chip binding. I would like to avoid inflating patchset since it is already a big series and tweaks to binding are small but significant. I will expand commit descriptions for each change included but if you insist on splitting this commit, I am perfectly fine with this too. Please let me know. > Thierry
