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 | |
| +-------+ |
+-------------+Thanks for adding the framer framework. I did not look into all the details, but the basic design looks good. Andrew
