Further discussion yielded the following set ofdecisions:- Move syscon_generic to BUS_PASS_DEFAULT- If a platform needs a syscon with different attach order or probebehavior, it should subclass syscon_generic and match on the SoC specificcompat string- When we come across a need for a syscon that attaches earlier but onlyspecifies compatible = "syscon", we should create a syscon_exclusive driverthat provides generic access but probes earlier and only matches if "syscon"is the only compatible. Such fdt nodes do exist in the wild right now, butwe don't really use them at the moment.Additionally:- Any syscon provider that has needs any more complex than a spinlock solelyfor syscon access and a single memory resource should subclass syscondirectly rather than attempting to subclass syscon_generic or add complexityto it. syscon_generic's attach/detach methods may be made public should theneed arise to subclass it with additional attach/detach behavior.We introduce aw_syscon(4) that just subclasses syscon_generic but probesearlier to meet our requirements for if_awg and implements #2 above for thisspecific situation. It currently only matches a64/a83t/h3 since these arethe only platforms that really need it at the time being.Discussed with: ianReviewed by: manu, andrew, bcr (manpages, content unchanged since review)Differential Revision: https://reviews.freebsd.org/D13793 List of files: /freebsd-12.1/sys/dev/extres/syscon/syscon_generic.h Sat, 13 Jan 2018 18:46:31 +0000 Kyle Evans <kevans@FreeBSD.org>
