Just because the HW is from Xilinx and has DMA in it's name does not mean it can be merged with some other Xilinx DMA driver... I suggest we stop this kind of argumentation as it is pointless and we look at the facts. The XDMA IP core really is very different from the other three Xilinx DMA engines which already have a driver in linux. Additionally as you can see, there are three supported Xilinx DMA engines and each of them has its own driver, so I see no reason for breaking this "rule" and try to violently merge the XDMA driver with one of the existing drivers (their maintainers would IMHO not be very happy...) > I don't understand your quoting style.

The story behind the weird quoting style is, I only have a web Outlook accesible through Citrix, where even copy&paste does not work... This is how things are if you work for the Volkswagen/Škoda corporate (Digiteq is a subsidiary of Škoda) like I do. The official mail addresses and their infrastructure is simply unusable for "serious" work. I even had to set up my own SMTP server in the Internet to actually send the patches... I will switch to different email address the next time I send the reworked patches and use some sane email client. There were two reasons for using the broken mail infrastructure: 1) By using the "official" company mail address I wanted to make clear that the driver is developed by the company producing the HW. 2) I didn't know that the web Outlook is that bad and only designed for the "corporate" style of replyies where you post your response on top of the previous message. TLDR - sorry for the "style", it will get better the next time I send the patches. M. INTERNAL
