But all of these .h files are only used by the code in this specific directory, no where else. So just mush them all together, having individual .h files doesn't really help anyone here, right? It's just more files for no good reason. And, it might help you see if you really need all of the info in those files :) > > For this initial move, only move the bus "core" code out, not the other > > stuff like: > > > >> drivers/irqchip/Makefile | 1 + > >> drivers/irqchip/irq-gic-v3-its-fsl-mc-msi.c | 119 +++ > > > > these should be a separate file move, right? > > This bus uses msi interrupts and this file contains glue code needed to > enable interrupts in the GICv3 irqchip.

Maybe > bus-devices/fsl-mc.txt makes more sense? Can you please suggest? It should be in .rst format, and tied into the documentation build somehow, I don't really know where new stuff is going, you should look at recent changes in that directory for more examples. thanks, greg k-h _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
