Hi,

This series adds RTC support for the Renesas RZ/V2H SoC.

The Renesas RZ/V2H RTC IP is based on the same RTCA3 IP as RZ/G3S
(r9a08g045), with the following differences:
- it lacks the time capture functionality
- the maximum supported periodic interrupt frequency is 128Hz instead
  of 256Hz
- it requires two reset lines instead of one

Best regards,
Ovidiu

v4:
- Renamed reset "rtc_rtest" -> "rtest".
- Added "vbattb" reset name to example node.

v3:
- Dropped all changes related to "max_user_freq", as it was removed from
  all drivers by:
  https://lore.kernel.org/all/20251101-max_user_freq-v1-0-c9a274fd6883@bootlin.com/

v2:
- Updated bindings and RTC dts node with "reset-names" property.
