[PATCH 0/5] Fixes for MST (daisy-chain and 4k tiles)
Hi Dave, I've been running with lockdep with these changes for over a week now. Just ran another test with our daisy-chain displays and the 4k tiled display with no deadlocks or lockdep prints (other than "RCU lockdep checking is enabled.").

I had started to fix the CSN/GUID one here a little while back but it's sitting on a laptop I can't access at the moment. But if you can test with lockdep, and it doesn't deadlock, then I'm happy to accept these..

[PATCH 0/5] Fixes for MST (daisy-chain and 4k tiles)
A couple of MST fixes to bugs in the framework that we encountered when testing with - three-display daisy-chain configurations - 4k tiled displays Andrey Grodzovsky (1): drm/dp/mst: Reverse order of MST enable and clearing VC payload table. Harry Wentland (2): drm: Add drm_fixp_from_fraction and drm_fixp2int_ceil drm/dp/mst: Calculate MST PBN with 31.32 fixed point Hersen Wu (1): drm/dp/mst: move GUID storage from mgr, port to only mst branch Mykola Lysenko (1): drm/dp/mst: change MST detection scheme drivers/gpu/drm/drm_dp_mst_topology.c | 180 +- include/drm/drm_dp_mst_helper.h | 25 ++--- include/drm/drm_fixed.h | 54 +- 3 files changed, 154 insertions(+), 105 deletions(-) -- 2.1.4
