On some platforms (like AM33xx), a special register (RTC_IRQWAKEEN)
is available to enable Alarm Wakeup feature. This register needs to be
properly handled for the rtcwake to work properly.

Platforms using such IP should set "ti,am3352-rtc" in rtc device dt
compatibility node.

may be use am3352-rtc here just to keep the platform device name and of
compatible in sync.
Correct. I will update the same in v2.

It is better to use the index defined above in the static initialization
so they remain in sync.
Sorry. I didn?t get this.
See example below I provided. If its still not clear, let me know what
is not clear.

Thanks for the clarification. In this case will it ok if I update the previous
member also.
You dont really reference [0] in omap_rtc_of_match[] so even if you
leave it as-is, that's fine with me. I am mostly concerned with the
index definitions and initialization order being out of sync and that's
really not an issue with [0].

Thanks,
Sekhar
