The Rust in Linux debate is over. The implementation has begun. In an email conversation, Linux's creator Linus Torvalds, told me, "Unless something odd happens, it [Rust] will make it into 6.1."

A journey in the RTC subsystem - Bootlin's blog
As part of a team effort to improve the upstream Linux kernel support for the Renesas RZ/N1 ARM processor, we had to write from scratch a new RTC driver for this SoC. The RTC subsystem API is rather straightforward but, as most kernel subsystems, the documentation about it is rather sparse. So what are the steps to write a basic RTC driver? Here are some pointers.
[...]
RTC counters rely on very precise clock sources to deliver accurate times. When the source is not matching the expected precision, which is the case of most cheap oscillators on the market. Some RTCs have a mechanism allowing to compensate for the frequency variation by incrementing or skipping the RTC counters at a regular interval in order to get closer to the reality.
