[PATCH v3 0/2] Add TechNexion EDM-G-IMX8M-PLUS SOM and WB-EDM-G carrier board support

From: Richard Hu
Date: Wed Jul 09 2025 - 01:50:13 EST


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

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).
