RTC hwmod is needed for proper operation of PM features like
rtcwake and rtc-only mode so reuse the am33xx rtc hwmod.

the ti,no-init flag in place that is introduced there this patch will cause the
am43x-epos-evm to fail to boot.

If that's so, shouldn't it appear in the series after patch 3, then?  
If only patches 1 and 2 are applied, then won't the boot be broken on 
am43x-epos-evm ?

Hmm yes you are correct that would be the case, seems I should have swapped the
order. I've gotten into the habit of putting dt patches last to enable what gets
introduced previously, guess it's not always the best thing to do. Thanks for
pointing this out.

Dave
