SH shouldn't be included it, we've never supported it. Out of the ones that do support this interface, I would guess that they should require little to no modification to work with drivers/rtc/rtc-cmos.c. Out of the ones that don't actually support this interface but never bothered updating the Kconfig bits.. none of h8300/microblaze/xtensa define any of the CMOS_READ/WRITE() accessors, so this has no chance at all of working there. Now to narrow that list down a bit more, both m32r and cris primarily use this interface for their ds1302 RTC, which I added a stub driver for in drivers/rtc/rtc-ds1302.c some time ago. With a bit of cleanup on the driver side and a bit of a push from the architecture side, they should also be able to just use the drivers/rtc version directly. I've offered to help with the conversion for these platforms before, but neither maintainer seemed terribly responsive. Which basically leaves just alpha, mips, mn10300, and x86. I would be surprised if these don't work with rtc-cmos already today. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to "rtc-linux".

It would be better to make this driver depend on simply CONFIG_WANT_RTC or similar and then select CONFIG_WANT_RTC in the relevant arch/foo/Kconfig files. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to "rtc-linux".
