What works for you works for me. We could add dummy fixed clocks in the DTS files if we wanted I suppose. The #interrupt-cells and interrupt-controller things we can just fix, but I wonder what the maintainers of these platforms are up to? Isn't Calxeda yours, and could Viresh fix up the SPEAr? Yours, Linus Walleij

I checked SPEAr and it is missing interrupt-controller at few places and clocks everywhere. Missing clocks should be fine as SPEAr doesn't get clocks from DT. And interrupt-controller can be just added, I don't think there would be any platform dependent side-affects ?

I'm pretty sure none of the distros are using the systems anymore and they were the main users for a while. Otherwise, I would have converted all the bindings it uses. > I checked SPEAr and it is missing interrupt-controller at few places and clocks > everywhere.

Right, but by the time I left ST in 2012, mainline clock's DT support wasn't there and the SPEAr core team got fired soon after that. No one was left in ST to do the porting, but there are still people using the SPEAr boards and there are products in market, so we can't delete the platform as well. So, no one is going to add clock DT support now. > > And interrupt-controller can be just added, I don't think there would be any > > platform dependent side-affects ? > > There shouldn't be. Okay, will send a patch for that then.
