The driver for the RTC SD3078 is not include in the kernel for Raspberry Pi.

On Debian the kernel can be found in the linux-modules-extra package

The SD3078 is used on the PiSugar2 battery pack/HAT (not really a HAT, but ok)

@rrooggiieerr (you should get that keyboard looked at) - it wasn't easy finding a datasheet, and my Chinese is non-existent, but the rpi-5.4.y tree should now have the relevant driver enabled and a supporting patch to the i2c-rtc overlay. It all compiles and the overlay loads the correct module, but beyond that I can't test it. Can you confirm that the I2C address is 0x32?

Great, thanks!

Yes, It's at 0x32

$ i2cdetect -y 1

How should I be able to test the new kernel, is there a testing repository that I can add to my sources.list?

Not for a kernel this new, no. It's not even in rpi-update yet. However, building your own kernel is actually quite easy if you follow our guide: https://www.raspberrypi.org/documentation/linux/kernel/building.md

I just ran rpi-update and configured the RTC. Seems to work!

Thanks for the quick followup!
