Hi,
This series adds support for audio using the QMC controller available in some Freescale PowerQUICC SoCs.
This series contains three parts in order to show the different blocks hierarchy and their usage in this support.
The first one is related to TSA (Time Slot Assigner). The TSA handles the data present at the pin level (TDM with up to 64 time slots) and dispatchs them to one or more serial controller (SCC).
The second is related to QMC (QUICC Multichannel Controller). The QMC handles the data at the serial controller (SCC) level and splits again the data to creates some virtual channels.
The last one is related to the audio component (QMC audio). It is the glue between the QMC controller and the ASoC component. It handles one or more QMC virtual channels and creates one DAI per QMC virtual channels handled.
Compared to the previous iteration https://lore.kernel.org/linux-kernel/20230113103759.327698-1-herve.codina@bo... this v4 series mainly: - updates code comment format (feedback received on v2 series and forgot to update in v3), - fixes bindings, - Replaces the fsl,tsa phandle and the fsl,tsa-cell-id property by a fsl,tsa-serial phandle and update the TSA related API, - Adds some missing lock in tsa_serial_connect() and tsa_serial_disconnect().
Best regards, Herve Codina
Changes v3 -> v4 - patches 2, 6 and 9 Update code comment format.
- patch 1 Fix some description formats. Add 'additionalProperties: false' in subnode. Move fsl,mode to fsl,diagnostic-mode. Change clocks and clock-names properties. Add '#serial-cells' property related to the newly introduced fsl,tsa-serial phandle.
- patch 2 Move fsl,mode to fsl,diagnostic-mode. Replace the fsl,tsa phandle and the fsl,tsa-cell-id property by a fsl,tsa-serial phandle and update the related API. Add missing locks.
- patch 5 Fix some description format. Replace the fsl,tsa phandle and the fsl,tsa-cell-id property by a fsl,tsa-serial phandle. Rename fsl,mode to fsl,operational-mode and update its description.
- patch 6 Replace the fsl,tsa phandle and the fsl,tsa-cell-id property by a fsl,tsa-serial phandle and use the TSA updated API. Rename fsl,mode to fsl,operational-mode.
- patch 8 Add 'Reviewed-by: Krzysztof Kozlowski krzysztof.kozlowski@linaro.org'
Changes v2 -> v3 - All bindings Rename fsl-tsa.h to fsl,tsa.h Add missing vendor prefix Various fixes (quotes, node names, upper/lower case)
- patches 1 and 2 (TSA binding specific) Remove 'reserved' values in the routing tables Remove fsl,grant-mode Add a better description for 'fsl,common-rxtx-pins' Fix clocks/clocks-name handling against fsl,common-rxtx-pins Add information related to the delays unit Removed FSL_CPM_TSA_NBCELL Fix license in binding header file fsl,tsa.h
- patches 5 and 6 (QMC binding specific) Remove fsl,cpm-command property Add interrupt property constraint
- patches 8 and 9 (QMC audio binding specific) Remove 'items' in compatible property definition Add missing 'dai-common.yaml' reference Fix the qmc_chan phandle definition
- patch 2 and 6 Use io{read,write}be{32,16} Change commit subjects and logs
- patch 4 Add 'Acked-by: Christophe Leroy christophe.leroy@csgroup.eu'
Changes v1 -> v2: - patch 2 and 6 Fix kernel test robot errors
- other patches No changes
