I'm looking to add a RTC to a custom 440gx-based board. The board
developer has indicated that they would prefer use an I2C device (vs.
eg. something like the DS1743 that's on the reference board).
Does anyone have any recommendations or comments? The primary
consideration is that it be easily supported with a 2.4.x kernel. The
only important function is the timekeeper function (though a WD
capability might be useful in the future).
Thanks in advance,
Ed

I got my board equipped with Epson's RX-8025 SA/NB RTC module.
I managed to get it working with a few hacks to a 8564 RTC driver
from Stefan Eletzhofer This RTC module is also from Epson.
So far everything works fine. I don't really know why board designers
decided for it but I suppose the main concern was price. :D
regards,
Ivica
