Hello Manivannan,

What is the status of this series?
Do you want to wait for designware-ep.c to be HDMA compatible before merging
the fixes? Do you expect us to do something? We can't work on the
designware-ep.c driver as we do not have such hardware.
Shouldn't fixes be merged as soon as possible?
