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 Changes v5 -> v6 - Patch 1 Add 'Reviewed-by: Krzysztof Kozlowski ' - Patch 2 New patch added fixing an MFD core issue. - Patch 3 (patch 2 in v5) Remove the pinmux part. Move registers definition to a header file and rework the definition. Use a regmap for register accesses Various minor fixes (typos, comments, ...) Fixed issues raised by checkpatch.pl --strict Removed debug prints. - Patch 4 (patch 3 in v5) No changes - Patch 5 New patch adding the PEF2256 pinmux part in the pinctrl subsystem. - Patch 6 (patch 4 in v5) Fixed issues raised by checkpatch.pl --strict - Patch 7 (patch 5 in v5) Updated according to files creation and move. Changes v4 -> v5 - Patch 1 Fix 'additionalProperties' and 'unevaluatedProperties' positions Fix sub-nodes names suffixes Changes v3 -> v4 - Patch 1 Merge the codec sub-node description. Move the 'allOf' property after the 'required' property. Rework the example to be more complete. - Patches 2 and 5 Drop of_match_ptr() - Patch 2 Add 'depends on OF' as pinconf_generic_dt_node_to_map_pin() needs OF support to be compiled (error raised by the kernel test robot). - Patch 4 Remove patch (merged in patch 1) Changes v2 -> v3 - Patch 1 Remove unneeded 'allOf' and quotes. Add several 'additionalProperties: false' Fix example (node name, interrupts and reg properties) Replace the lantiq,sysclk-rate-hz property by sclkr and sclkx clocks. Define 'lantiq,frame-format' property in top level. Move to MFD - Patch 2 Fix some #define. Compact the register accessor helpers. Rework pef2256_get_version(). Merge v1.2 and v2.x GCM setup functions into one pef2256_setup_gcm(). Update comments, avoid duplicates and change some conditionals. 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 - Patch 4 Remove, merged with patch 7 - Patch 4 (patch 5 in v2) Update title and description. Remove incorrect SPI reference. Remove the 'lantiq,pef2256' phandle. Fix commit log - Patch 5 (patch 6 in v2) Remove devm_pef2256_get_byphandle(). Fix commit log - Patch 6 (patch 7 in v2) Merge v2 patch 4. One entry only for PEF2256 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.
