Yes exactly, it is a CPM1 support (kind of previous version of QE).
Do you think that fixing the subject is enough or do I need also to create a new directory drivers/soc/fsl/cpm/ and move these drivers (TSA and QMC) in this new directory.
The alternative could be to leave this driver in drivers/soc/qe/ and rename it to cpm-tsa.c.
For information, we have some plan to have this driver working with QE (not done yet).

Yes but this can be seen as an extension only used by drivers/net/wan/fsl_ucc_hdlc.c and it supports QE only.
Not sure that qe-tdm.c will fit well if several other drivers instances use it.
