Subject: [PATCH v5 00/31] Add support for QMC HDLC,
 framer infrastructure and PEF2256 framer

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.
