Great, thats good co-operatation and communications, sometimes though it is not so smooth.

We need to always try to find middle ground and co-operate in positive ways. On the "we have a standard" front, well when standards get in the way of forward progress they are often side stepped. Maybe this standard is not such a good standard and warts are going to form around it. I have seen some discusssion at least on ways to improve the current situation, hopefully someone takes them and runs with them. Others have pointed out they do not like the current model in that it gets in the way of developement progress. I can see this point. I can see phk's points, and I can see your points. IMHO if we shove the standard down our own throats we are in effect cutting our hands off in the process, not somethig we really want to do is it? > > (I personally hate having to edit the dts/recompile/reboot for every > > test hardware change; it makes breadboarding things up kinda > > hilariously annoying.) > > Use overlays then.
