[PATCH v4 0/2] Add TechNexion EDM-G-IMX8M-PLUS SOM and WB-EDM-G carrier board support

[Richard Hu]

Add initial support for TechNexion EDM-G-IMX8M-PLUS SOM and WB-EDM-G
carrier board.

Changes in v4:
- Incorporate review feedback from Shawn and apply further cleanups to DTS
  style and node naming.

in patch 2/2:
       - Addressed formatting issues by adding newlines and removing
         unnecessary backslashes.

       - Removed the lvds-backlight node for the optional display panel,
         which will be handled by a device tree overlay.

       - Aligned several node names with DT conventions. For example:
         - `codec@1a` -> `audio-codec@1a`
         - `gpio-leds` -> `leds`
         - `pcie0-refclk` -> `clock-pcie-ref`
         - `wlreg-on` -> `regulator-wl-reg-on`

Changes in v3:
- The changes address DT schema warnings, remove unused regulators, and
  improve the overall structure.

in patch 2/2:
       - Fixed DT Schema Warnings: Renamed the i2c-gpio node to i2c-0 to
         resolve a naming convention warning reported by Rob's checker.

       - Removed Unused Regulators: Removed several unused regulator-fixed
         nodes for LVDS, backlight, ethernet power, and the OTG VBUS, as
         pointed out by Peng Fan.

       - Added EEPROM Nodes: Added device tree nodes for the EEPROMs
         present on both the SOM and the baseboard.

       - Node Reorganization: Relocated the iomuxc node to the end of the
         device tree files for better readability.

Change in V2:
- Ensured accurate `To:` and `Cc:` addresses by utilizing
  `b4 prep --auto-to-cc`. (Thanks to Krzysztof Kozlowski for the
  tip on this command and helpful suggestion from Rob Herring).

in patch 1/2:
        - Add Acked-by tag.

in patch 2/2:
        - Generic Node Naming: Refactored device tree node names for I2C
          GPIO expanders, the USB Type-C controller, and the PMIC to adhere
          to generic naming conventions (e.g., `gpio@21`, `usb-typec@67`,
          `pmic@25`).

        - Removed Unused SPI Node: Eliminated the `spidev1` node due to an
          incorrect and non-existent compatible string (`rohm,dh2228fv`).

        - Minor formatting improvements (e.g., whitespace, indentation).

Hi Shawn,

This is just a gentle ping to follow up on this patch series, in case it got buried in other emails.

Odd to see GPL-3.0 (and newer as well). Are you sure this is what you want?

Wrong define. And the flag is not NONE, either.

You just copied same bug from some very old (5 years?) code.
