You can check hps_io.v signals. There you will find RTC info.
It would be more clear if you would tell what you want to do. Are you writing core which needs RTC?

But i strongly suggest to use recommended chips. They are not hard to find and there is board already for them.
Otherwise you will have to modify and compile every new kernel release.

Looks like having no issues (just running for some hours).
Let's see how it behaves over the weekend on battery.

I've used P/N AD7415ARTZ-0500 on my board.

Currently there is no software support for temp sensor and i cannot tell if it will be easy to support different addresses or not.
