Subject: [PATCH v2 0/3] Add support for Nuvoton ma35d1 rtc controller

From: Jacky Huang <ychuang3@...oton.com>

This patch series adds the rtc driver for the nuvoton ma35d1 ARMv8 SoC.
It includes DT binding documentation, the ma35d1 rtc driver, and device
tree updates.

The ma35d1 rtc controller provides real-time and calendar messaging
capabilities. It supports programmable time tick and alarm match
interrupts. The time and calendar messages are expressed in BCD format.

This rtc driver has been tested on the ma35d1 som board with Linux 6.5-rc2.

v2:
  - Updated nuvoton,ma35d1-rtc.yaml
    - Modified patch title and fixed typo
    - Added reference to rtc.yaml
    - Used unevaluatedProperties instead of additionalProperties
  - Modified rtc driver
    - Used dev_err_probe()
    - Removed ma35d1_rtc_remove()
    - Made other minor fixes
