Looking for mpc8xx QMC driver

[leroy christophe]

I'm looking for someone having some QMC driver and/or some experience 
with the QMC (QUICC Multichannel Controlleur) on mpc8xx.
This is because we are trying to implement audio interface to codecs via 
the TDM bus using the QUICC. At the time being we are facing a major 
issue which is that after some time, we don't get any interrupts 
anymore, and we are not able to find what we did wrong.
