This patch series is submitted to add GMAC support for Nuvoton MA35D1
SoC platform. This work involves implementing a GMAC driver glue layer
based on Synopsys DWMAC driver framework to leverage MA35D1's dual GMAC
interface capabilities.

Overview:
  1. Added a GMAC driver glue layer for MA35D1 SoC, providing support for
  the platform's two GMAC interfaces.
  2. Added device tree settings, with specific configurations for our
  development boards:
    a. SOM board: Configured for two RGMII interfaces.
    b. IoT board: Configured with one RGMII and one RMII interface.
  3. Added dt-bindings for the GMAC interfaces.

v6:
  - Update dwmac-nuvoton driver
    - Use NVT as the previx for all functions, structs, and defines.
    - Remove unnecessary comments.

v5:
  - Update yaml
    - Remove the properties already defined in snps dwmac.
  - Update dwmac-nuvoton driver
    - Add a comment to explain the override of PMT flag.

v4:
  - Update yaml
    - Remove unnecessary property 'select'.
    - Remove unnecessary compatible entries and fix items.
    - Specify number of entries for 'reg'.
    - Remove already defined property 'phy-handle'.
    - Update example.
    - Modify the property internal path delay to match the driver.
  - Update dtsi
    - Move 'status' to be the last property.
  - Update dwmac-nuvoton driver
    - Use remove instead of remove_new.
    - Use dev_err_probe instead.

v3:
  - Update yaml
    - Fix for dt_binding_check warnings & errors.
    - Add compatible in snps dwmac.
  - Update dtsi
    - Update dtsi to follow examples in yaml.
  - Update dwmac-nuvoton driver
    - Fix for auto build test warnings.
    - Invalid path delay arguments will be returned.

v2:
  - Update yaml
    - Rename file to align with the compatible property.
    - Add an argument to syscon to replace mac-id,
      with corresponding descriptions.
    - Use tx-internal-delay-ps and rx-internal-delay-ps properties for
      configurable path delay with corresponding descriptions,
      allowing selection between GMAC internal and PHY.
    - Add all supported phy-mode options.
    - Remove unused properties.
  - Update dtsi
    - Modify syscon configuration to include an argument for
      GMAC interface selection.
  - Update dwmac-nuvoton driver
    - Remove redundant device information print statements.
    - Remove non-global parameters.
    - Retrieve GMAC interface selection from the syscon argument.
    - Parse Tx and Rx path delays by correct properties.
    - Update configurations to support Wake-on-LAN.

Would be good if you could reply to Christophe's question.

Then please rebase on top of net-next/main and repost.
The first patch doesn't currently apply cleanly.
Please leave out the second patch, it has to go via
the appropriate platform tree, rather than the networking
tree.

I got it. Thank you!
