[PATCH v3 0/3] arm64: Realtek RTD1295 RTC

This series adds the RTC for the Realtek RTD1295 SoC.
Based on my RTD1295 clk series.

There being no public source code for RTD1295, the implementation is based on
register offsets seen in the vendor DT, as well as older mach-rtk119x code
published by QNAP.

v3 drops a redundant spinlock and refactors a helper.

The DT node depends on the clk series for clock index and header.

Have a lot of fun!


v2 -> v3:
* Dropped spinlock (Andrew)
* Improved year_days vs. days_in_year readability

v1 -> v2:
* Updated rtc driver to no longer use open/release (Alexandre)
* Cleaned up debug output (Andrew)
* Avoided COMPILE_TEST division errors (kbuild)
* Various cleanups and extensions
