Patch Review

This patch has a `Reviewed-by: Krzysztof Kozlowski` so the DT binding itself is likely in good shape. A few observations:

1. **Missing `enable-gpios` in the binding**: The driver in patch 2 acquires an optional `"enable"` GPIO via `devm_gpiod_get_optional(dev, "enable", GPIOD_OUT_HIGH)`, but the binding YAML has no `enable-gpios` property. If the hardware can use an enable GPIO, it should be documented in the binding. If it isn't actually needed, the driver shouldn't be requesting it.

2. **Output port descriptions are vague**: All three output ports (port@1, port@2, port@3) have nearly identical descriptions:
   ```yaml
   port@1:
     description:
       DP port for DP output from bridge
   port@2:
     description:
       Additional DP port for DP output from bridge
   ```
   It would be helpful to clarify if these correspond to specific physical connectors on the chip or are functionally interchangeable, and whether they can be HDMI outputs as well (the title says "DP1.4/HDMI2.0").

3. **No `allOf` with `i2c-controller.yaml`**: Minor — some bindings for I2C devices include an explicit `$ref` to `i2c-controller.yaml` or the `unevaluatedProperties: false` pattern, though this isn't strictly required with `additionalProperties: false`.
