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.

This v2 series fixes issues raised by the kernel test robot
  - devm_platform_ioremap_resource symbol undefined
  - duplicate const qualifier
  - Block quote ends without a blank line

Best regards,
Herve Codina

Changes v1 -> v2
  - Patch 2
    Remove duplicate const qualifiers.
    Add HAS_IOMEM as a dependency

  - Patch 3
    Fix a "Block quote ends without a blank line; unexpected unindent"
    syntax issue.
