This is needed to properly deallocate port payload after downstream branch get unplugged. In order to do this unplugged MST topology should be preserved, to find first alive port on path to unplugged MST topology, and send payload deallocation request to branch device of found port. For this mstb and port kref's are used in reversed order to track when port and branch memory could be freed. Added additional functions to find appropriate mstb as described above.

Previous implementation does not handle case below: boot up one MST branch to DP connector of ASIC. After boot up, hot plug 2nd MST branch to DP output of 1st MST, GUID is not created for 2nd MST branch. When downstream port of 2nd MST branch send upstream request, it fails because 2nd MST branch GUID is not available. New Implementation: only create GUID for MST branch and save it within Branch.

1. Get edid for all connected MST displays, not only on logical ports, in the same thread as MST topology detection is done: There are displays that have branches inside w/o logical ports. So in case another SST display connected downstream system can end-up in situation when 3 DOWN requests sent: two for ‘remote i2c read’ and one for ‘enum path resources’, making slots full. 2. Call notification callback in one place in the end of topology discovery/update: This is done to reduce number of events sent to userspace in case complex topology discovery is going, adding multiple number of connectors; 3. Remove notification callback call from short pulse interrupt processing function: This is done in order not to block interrupt processing function, in case any MST request will be made from it. Notification will be send from topology discovery/update work item.

Our PBN value overflows the 20 bits integer part of the 20.12 fixed point. We need to use 31.32 fixed point to avoid this. This happens with display clocks larger than 293122 (at 24 bpp), which we see with the Sharp (and similar) 4k tiled displays.

drm_fixp_from_fraction allows us to create a fixed point directly from a fraction, rather than creating fixed point values and dividing later. This avoids overflow of our 64 bit value for large numbers. drm_fixp2int_ceil allows us to return the ceiling of our fixed point value.

Commit a9fa8528 ("drm/exynos: dp: add of_graph dt binding support for panel") made the Exynos DP DT binding more consistent since the OF graph could be used to lookup either a panel or a bridge device node. Before that commit, a panel would be looked up using a phandle and a bridge using the OF graph which made the DT binding not consistent. But the patch broke the later case since not finding a panel dev node would cause the driver's to do a probe deferral instead of attempting to lookup a bridge device node associated with the remote endpoint. So instead of returning a -EPROBE_DEFER if a panel is not found, check if there's a bridge and only do a probe deferral if both aren't found.
