Subject: [PATCH v3 0/6] Add the Lantiq PEF2256 audio support
Date:   Wed, 22 Mar 2023 14:46:48 +0100

Hi,

This series adds support for audio using the Lantiq PEF2256 framer.

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 first part of this series (patches 1 to 4) adds the Lantiq PEF2256
driver core.
The second part (patches 5 to 7) adds the audio support using the Lantiq
PEF2256 driver core.

The consumer/provider relation between the codec and the driver core
allows to use the PEF2256 framer for other purpose than audio support.

Compared to the previous iteration
  https://lore.kernel.org/linux-kernel/20230316122741.577663-1-herve.codina@bootlin.com/
This v3 series mainly:
  - takes into account pef2256.c modifications suggested by Christophe.
  - fixes binding
  - Moves to MFD.
  - Merges MAINTAINERS entries

Best regards,
Herve Codina
