Hello,
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.
v4 adds a missing clk_put().
The DT node depends on the clk series for clock index and header.
More experimental patches at:
https://github.com/afaerber/linux/commits/rtd1295-next
Have a lot of fun!
Cheers,
Andreas
v3 -> v4:
* Added clk_put() (Alexandre)
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
