This driver doesn't seem to have exported symbols, and no in-kernel users. So how will it be used? Usually we ask to hold off until the consuming side/drivers are also ready. Also, is there a reason this is under drivers/soc/ instead of somewhere more suitable in the drivers subsystem? It's not "soc glue code" in the same way as drivers/soc was intended originally. -Olof -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Yeah the TI driver series has been reviewed and was 'waiting' for dependency to be resolved before I could apply them FWIW here is the series under consideration: https://lore.kernel.org/dmaengine/20191223110458.30766-1-peter.ujfalusi@ti.com/ > > Also, is there a reason this is under drivers/soc/ instead of somewhere more > > suitable in the drivers subsystem?

Ok -- might have been useful to get that in the tag description for context.

Navigator was also similar example. Hmm. At some point we'll have to push the brakes on this, since drivers/soc can't become a catch-all for random stuff like the old mach directories were. But it's tricky to tell just when -- sometimes you have to let the mess show up too. I'll merge this when I do the next pass (today, likely). -Olof -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.
