I have no objections to the patch, it makes a lot of sense, but I think the reasoning above is a bit questionable, as a lot of the other host drivers (at least tegra, mvebu and xgene, probably more) equally support endpoint mode and remain in the same directory. Any suggestion to what we should do with them?

I'm not sure of the exact IP's used by these SoCs. Now that we decided to group the drivers by IPs used, the best would be identify the IPs used in these SoCs and create a separate directory for each of the IPs. If the vendors own IP is used, then create a directory with the name of the vendor?. I'm sure such a change would increase the number of directories but I'm not sure what else to do here.

In case of designware based drivers you already did the clean up nicely. Next would be, like Arnd is sugesting, to do the same to the others. If they are all self-contained I suggest we leave them as they are and in the future if a endpoint variant driver comes up for any of them, we can suggest to add a folder with the vendor or SoC name in order to follow the rule. What do you think?

What do you think? That's my idea as well. Arnd, do you think it's okay not to disturb other drivers/directories until endpoint support is added to those drivers?
