+title: Lantiq PEF2256 codec

+description: |
- Codec support for PEF2256.
- The Lantiq PEF2256, also known as Infineon PEF2256 or FALC56, is a framer and
- line interface component designed to fulfill all required interfacing between
- an analog E1/T1/J1 line and the digital PCM system highway/H.100 bus.
- The codec support allows to use some of the PCM system highway time-slots as
- audio channels to transport audio data over the E1/T1/J1 lines.
- The time-slots used by the codec must be set and so, the properties
- 'dai-tdm-slot-num', 'dai-tdm-slot-width', 'dai-tdm-slot-tx-mask' and
- 'dai-tdm-slot-rx-mask' must be present in the ALSA sound card node for
- sub-nodes that involve the codec. The codec uses 8bit time-slots.
- 'dai-tdm-tdm-slot-with' must be set to 8.
- The tx and rx masks define the PEF2256 time-slots assigned to the codec.
- The PEF2256 codec node should be a child of a PEF2256 node.
- Refer to the bindings described in
- Documentation/devicetree/bindings/mfd/lantiq,pef2256.yaml
+allOf:
- $ref: dai-common.yaml#
+properties:
- compatible:
- const: lantiq,pef2256-codec
- '#sound-dai-cells':
- const: 0
You do not have here any resources, so the entire binding can be dropped and merged into the parent.
Best regards, Krzysztof
Ok, Do you expect all these properties (except compatible) merged at the parent level or may I keep a child node with these properties including the compatible property (ie. yaml file merge).
