Some legacy RTC IP revisions has a power-up reset flag in the status
register that later revisions lack.

As this flag is always read back as set on later revisions (or is
overloaded with a different flag), make sure to only clear the flag and
print the info message on legacy platforms.

oh, btw. This should be done for DT probes too.
What do you mean? This is for DT probes (of "ti,da830-rtc" and
"ti,am3352-rtc"). DT probing of legacy RTC IPs is currently not
supported.

Are you suggesting I should add a new compatible string for that?
it seemed to me that you're only passing the new flag through
platform_device_id table, not DT table. Did I miss something ?
Ah, that's just the way the driver currently encodes the IP revision
differences. The platform_device_id entries are references from
of_device_id data. Should probably clean that up as well.
oh, alright :-)
Thanks again for the review. I'll post a new version when I'm back from
no problem.
