The Lantiq PEF2256 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.

+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

You do not have here any resources, so the entire binding can be dropped and merged into the parent.
