Hmm... that's new. Since when are device tree additions expected to cause these kinds of splats? Anyway, I did apply these because I had seen at least some of the memory controller driver patches appear in linux-next and hence had assumed that the whole series had gone in, not realizing there was anything left to do. Krzysztof, what's your schedule for the memory controller tree? My recollection is that this will feed into ARM SoC, so if the -rc6 dead- line applies like it does for platforms, then I may need to revert the DT patch that causes this so that we don't have to drag this along through all of the release cycle. If there's still time for you to send that PR, perhaps we can get the remainder of the Tegra interconnect series merged for v5.11 as well? Thierry

I was waiting for last acks from Rob and you and actually planned to merge everything this week (weekend at the latest). Indeed it slightly slipped away... the v11 was reposted late. It could still make till v5.11, if I send the PR now (still around 3 weeks before merge window). However I saw now your comments for the patch 4/10 from v11. I'll take patches 1-3 for now. Best regards, Krzysztof
