Subject: [PATCH v6 0/7] Add the Lantiq PEF2256 audio support
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 fixing a MFD core issue at patch 2.
The patch 5 adds the PEF2256 pinmux support.
The patch 6 adds the audio support using the Lantiq PEF2256 driver core.
The last patch adds myself as the PEF2256 maintainer.
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/all/20230328092645.634375-1-herve.codina@bootlin.com/
This v6 series mainly:
- Use regmap
- Move the pinmux part to the pinctrl subsystem
- Move register definitions to header files.
- Split pef2256_setup_e1() in several parts.
- Fixed issues raised by checkpatch.pl.
- Removed debug prints.
Best regards,
Herve Codina

Remove the carrier spinlock and use atomic_t.
Make exported symbol consistent and use EXPORT_SYMBOL_GPL.
Remove the no more needed pef2256_get_byphandle() and
devm_pef2256_get_byphandle().
Replace the lantiq,sysclk-rate-hz property by sclkr and sclkx clocks.
Move to MFD
