Currently the prm devices are handled by mach-omap2 and all this does it to prevent hardcoding of irq numbers within the current code. > > Would a simple driver be doable that parses the compatible > flags, takes care of the IRQ chaining, and gets some SoC specific > function pointers as auxdata? Tero has been trying to move PRM/CM stuff to a separate drivers of thier own. With that there wont be a need for auxdata even. - this current logic will get merged with that driver - if and when that is ready. I am not actually adding any driver logic here - just reusing the logic and providing glue for using dt description instead of hardcoded logic that the current mach-omap2 driver does. > > That would allow further work later on to remove the auxdata > dependencies possibly. -- --- Regards, Nishanth Menon -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
