Jon,

I applied all these patches and it fixes build warning and also I have
tested it on Bone platform without any issues.

I also ran parse on this and saw further warning,

  CHECK   arch/arm/mach-omap2/timer.c
arch/arm/mach-omap2/timer.c:193:13: warning: symbol 'omap_dmtimer_init'
was not declared. Should it be static?
arch/arm/mach-omap2/timer.c:213:12: warning: symbol
'omap_dm_timer_get_errata' was not declared. Should it be static?

Below patch fixes that too, feel free to merge it into your's

Thanks,
