RTC Chipsets

What chipsets are compatible with RISC OS? Is there a list somewhere?

DS1307 works (address &68)
DS3231 (address &68) on the Witty Pi also works (rollover address is a bit higher as it has more registers)

This page gives a bit more info suggesting that the following are all supported:
TPS65950-compatible real-time clock (OMAP3)
TWL6030-compatible real-time clock (OMAP4)
DS1307 real-time clock (Iyonix)
PCF8583 real-time clock (Risc PC)
DS1307 real-time clock (Pi)

Perfect, thanks for the info.

I went with the DS3231 RTC
