[PATCH 00/26] Add support for QMC HDLC, framer infrastruture and PEF2256 framer
by Herve Codina 26 Jul '23

26 Jul '23

Hi, I have a system where I need to handle an HDLC interface and some audio data. The HDLC data are transferred using a TDM bus on which a PEF2256 (E1/T1 framer) is present. The PEF2256 transfers data from/to the TDM bus to/from the E1 line. This PEF2256 is connected to a PowerQUICC SoC for the control path and the TDM is connected to the SoC (QMC component) for the data path. From the QMC HDLC driver, I need to handle HDLC data using the QMC, carrier detection using the PEF2256 (E1 line carrier) and set/get some PEF2256 configuration. The QMC HDLC driver considers the PEF2256 as a generic framer. It performs operations that involve the PEF2256 through the generic framer API. The audio data are exchanged with the PEF2256 using a CPU DAI connected to the TDM bus through the QMC and the PEF2256 needs to be seen as a codec in order to be linked to the CPU DAI. The codec handles the carrier detection using the PEF2256 and reports the carrier state to the ALSA subsystem using the ASoC jack detection. The codec, even if instantiated by the PEF2256 driver, considers the PEF2256 as a generic framer. The generic framer has: - 2 consumers (QMC HDLC drv and codec) - 1 provider (PEF2256) So, the design is the following: +------------------+ +---------+ | QMC | <- TDM -> | PEF2256 | <-> E1 +---------+ | +-------------+ | | | | CPU DAI | <-data--> | QMC channel | | | | +---------+ | +-------------+ | | | +--------------+ | +-------------+ | | | | QMC HDLC drv | <-data--> | QMC channel | | | | +--------------+ | +-------------+ | | | ^ +------------------+ | | | +--------+ +-------------+ | | +-> | framer | <-> | PEF2256 drv | <- local bus ->| | | | | | +---------+ +-> | | | | | +--------+ | +-------+ | +-------------------> | codec | | | +-------+ | +-------------+ Further more, the TDM timeslots used by the QMC HDLC driver need to be configured at runtime (QMC dynamic timeslots). Several weeks ago, I sent two series related to this topic: - Add the Lantiq PEF2256 audio support [1] - RFC Add support for QMC HDLC and PHY [2] This current series is a rework of these two series taking into account feedbacks previously received. In order to implement all of this, I do the following: 1) Perform some fixes (patches 1, 2) 2) Introduce the QMC HDLC driver (patches 3, 4, 5) 3) Add QMC dynamic timeslot support (patches 6 - 16) 4) Add timeslots change support in QMC HDLC (patch 17) 5) Introduce framer infrastructure (patch 18) 6) Add PEF2256 framer provider (patches 19, 20, 21, 22, 23) 7) Add framer codec as a framer consumer (patch 24) 8) Add framer support as a framer consumer in QMC HDLC (patch 25, 26) The series contains the full story and detailed modifications. If needed, the series can be split and/or commmits can be squashed. Let me know.

alsa-project/alsa-ucm-conf issue #337 was edited from motomyslen: I tried with `alsa-ucm-conf-1.2.9` but microphone still not working. Front audio panel detects headphones but no sound and mic not working as well. If I'm not wrong ID of my device is `0db0:a073` and it was added a year ago to `USB-Audio.conf` but still something is wrong. Do I need to install alsa-utils 1.2.9?
