It was nice knowing Raspberry Pi while they lasted. Going to suck losing something that has changed the homegrown embedded system hobby forever.

Only a fraction of it is RTCs. What is in the Pi overlays folder is from everything. Not even all the DT I2C RTCs. There is loads of ADCs, DACs, IO extenders, all sorts.
It’s really annoying you can’t do DT on x86 Linux. It’s a bit of a gap in the platform. It would make Linux ARM based developer’s lives easier.
These should all work without kernel drivers. For example, here’s a user space python library for ADS1*15 ADCs, or Nuvoton MS51 IO Expanders. Unless you need very specific timing or require the kernel to know about it, you shouldn’t need a kernel driver.
