Claude review: dt-bindings: display: bridge: ldb: Require reg property only for i.MX6SX/8MP LDBs

Patch Review

**Changes summary:**
1. Adds `minItems: 1` to the `reg` property definition
2. Removes `reg` from the global `required` list
3. Adds a new `if/then` block requiring `reg` only for `fsl,imx6sx-ldb` and `fsl,imx8mp-ldb`
4. Restructures the `reg-names` conditional from a negated check ("not imx6sx") to a positive match ("only imx8mp")

**Analysis:**

The logic changes are correct:

- **Before:** `reg` required for all three variants (imx6sx, imx8mp, imx93); `reg-names` required for imx8mp and imx93.
- **After:** `reg` required only for imx6sx and imx8mp; `reg-names` required only for imx8mp.

This is consistent — imx93 LDB needs neither `reg` nor `reg-names` since it lives under a syscon parent.

**Minor nits:**

1. `minItems: 1` on `reg` is technically redundant (1 is the implicit minimum for array properties in dt-schema), but it's harmless and clarifies intent alongside `maxItems: 2`. Not worth blocking over.

2. The commit message says "it's" (line 153 of the mbox) where it should be "its":
```
LDB's parent device could be a syscon which doesn't allow a reg property
to be present in it's child devices
```
Should be `its child devices`.

3. The restructuring of the `reg-names` conditional is a nice cleanup. The old form:
```yaml
  - if:
      not:
        properties:
          compatible:
            contains:
              const: fsl,imx6sx-ldb
    then:
      required:
        - reg-names
```
used a negation that implicitly required `reg-names` for any future compatible added to the schema. The new positive match:
```yaml
  - if:
      properties:
        compatible:
          contains:
            const: fsl,imx8mp-ldb
    then:
      required:
        - reg-names
```
is more explicit and safer for future compatible additions, which is the right direction.

**Verdict:** Looks good. The Fixes tag is appropriate. Only the "it's → its" typo in the commit message is worth mentioning to the author.
