Subject[PATCH v2 5/6] dt-bindings: input: zinitix: Document touch-keys support
Date
In some configurations the touch controller can support the touch-keys.
Document the linux,keycodes property that enables those keys and
specifies the keycodes that should be used to report the key events.

Signed-off-by: Nikita Travkin <nikita@trvn.ru>
---
Changes in v2:
- Include input.yaml schema at the top level instead of at the
property. (Seems like I still can't think of the schema as device
and not implementation-specific thing...)
- Reword the description to be more informative.
