In general, for new functionality where needing both the driver change and a DT change to enable it (or a driver change and a config change to enable it), we have been merging the changes separately between driver trees and arm-soc. I.e. things will be in place, but not enabled, until both sides land. Main reason for doing so is to cut down on arbitrary dependencies between the trees, since there can sometimes end up being a lot of them.Well, makes sense too and it is the least problematic approach. :-)quoted
Since DT should strive for being backwards compatible (i.e, a driver change shouldn't require a DT change for the kernel to not regress functionally), this has been working pretty well.Ok.quoted
However, if there's some other reason to share a base between the two trees, we can do that. For most cases we've found that it's not needed though. So let us know what you prefer here.No, I just wanted to make sure drivers can still function when they go to linux-next. But I certainly can get on board with keeping drivers and DT changes separate as it requires no sync and the short period of time when they don't load in linux-next, is perfectly ok.
Ok, sounds good.
So can I assume you guys are going to pick up: https://lkml.kernel.org/r/1538667328-9465-7-git-send-email-manish.narani at xilinx.com https://lkml.kernel.org/r/1540447621-22870-6-git-send-email-manish.narani at xilinx.com
Yeah, Michal should pick those up for his platform and send them in to us (or let us know if he wants us to take them directly, but usually they come in through platform maintainers sending us pull requests).
? I can then pick up the rest. And I'll be ignoring DT stuff sent to me from now on and concentrate on the EDAC drivers, assuming former will go through your tree. Sounds good?
Yeah, that's the way we've been trying to do for various subsystems and it's been working pretty well. Of course, if there's need to coordinate more closely for something in the future we'll be happy to do so. -Olof
