Same, that's QMC for CPM for the time being, should that be made clear 
in the subject ?

QE also has QMC and this driver might be used for QE QMC as well with 
some enhancement, maybe that could be explained here ?

I see you are using in_be16(), out_be16() etc ....
That's specific to powerpc arch, maybe it is better to use ioread16be, 
iowrite16be() etc ....
See commit 3f39f38ea91d ("soc: fsl: qe: replace qe_io{read,write}* 
wrappers by generic io{read,write}*") and commit 6ac9b61786cc ("soc: 
fsl: qe: introduce qe_io{read,write}* wrappers") for information.

In some places, you comments use the network style, not the generic style.
