A framer can be connected to the QMC HDLC.
If present, this framer is the interface between the TDM used by the QMC
HDLC and the E1/T1 line.
The QMC HDLC can use this framer to get information about the line and
configure the line.

Add an optional framer property to reference the framer itself.

Why not fully describe the hardware in one patch in this series, rather
than split this over two different ones?

Now you've defined this property twice. Please avoid doing that.

I don't see what you mean.

I previously defined the framer property at the framer-codec node as it is
a framer consumer (it was a mistake because this framer-codec node is a child of
the framer node but that's an other story).

Here, at the qmc-hdlc node, I define this property in order to use the framer as a
consumer too.

What is wrong ?

Best regards,
Hervé
