[PATCH v3 2/6] dt-bindings: pinctrl: Document Tegra238 pin controllers

pshete
2026-04-27T13:43:33Z

Tegra238 contains two pin controllers. Document their compatible strings
and describe the list of pins and functions that they provide.

Changes in v3:
- Wrap commit message to 75 chars per line (v2 was too short).
Changes in v2:
- Add a 'required:' block listing 'compatible' and 'reg'.
- Switch top-level 'unevaluatedProperties: false' to
'additionalProperties: false'.
