But with m68k converted over it might be time for these two arm platforms to either be converted to the clocksource API or to be dropped..
You could remove the old arch_gettimeoffset API without dropping any platforms. If no-one converts a given platform to the clocksource API it would mean that the default 'jiffies' clocksource will get used on that platform. Clock resolution and timer precision would be degraded, but that might not matter. Anyway, if someone who has this hardware is willing to test a clocksource API conversion, they can let me know and I'll attempt that patch. --
