[PATCH v2 0/3] watchdog: Add support for Andes ATCWDT200

[CL Wang <cl634@andestech.com>]

This series adds support for the Andes ATCWDT200 watchdog timer.

The driver integrates with the Linux watchdog framework and supports:
  - Basic watchdog operations (start, stop, ping, set_timeout).
  - Programmable reset and interrupt intervals.
  - Automatic detection of the supported interrupt timer bit-width.
  - System reset via the watchdog restart handler.

Changes in v2:
  - dt-bindings:
    - Drop redundant text "including supported properties..." from the
      commit message.
    - Clarify the relationship between ATCWDT200 IP and SoCs (AE350/Qilai)
      in the commit message.
    - Add missing type definition ($ref: uint32), enum constraint, and
      description for 'andestech,clock-source' property. 
  - watchdog: atcwdt200:
    - Use devm_clk_get_enabled() instead of devm_clk_get() and
      clk_prepare_enable()
    - Drop unnecessary "andestech,qilai-wdt" compatible
    - Remove .owner assignment from platform_driver
    - Simplify resume error handling
