Mykola Lysenko 91a25e4631 drm/dp/mst: deallocate payload on port destruction
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.

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.

Mykola Lysenko cfcfa086d4 drm/dp/mst: change MST detection scheme
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.

Javier Martinez Canillas 37e110625e drm/exynos: dp: Fix panel and bridge lookup logic
Commit a9fa852886 ("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.

Arnd Bergmann 010848a73f drm: exynos: make PM functions as __maybe_unused
The newly added runtime-pm support for exynos-drm encloses the
pm functions in an #ifdef, but not the functions that are called
from them and nowhere else, which produces warnings:

drm/exynos/exynos_drm_dsi.c:733:13: warning: 'exynos_dsi_disable_clock' defined but not used [-Wunused-function]
 static void exynos_dsi_disable_clock(struct exynos_dsi *dsi)

 static void exynos_dsi_disable_irq(struct exynos_dsi *dsi)
             ^

This removes the #ifdef and instead marks the functions as
__maybe_unused, so gcc can silently discard them and all called
functions when CONFIG_PM is disabled.

exynos_mixer.c:1289:61: error: 'exynos_mixer_resume' undeclared here (not in a function)
  SET_RUNTIME_PM_OPS(exynos_mixer_suspend, exynos_mixer_resume, NULL)

This removes the #ifdef and instead marks the functions as
__maybe_unused, which does the right thing in all cases and
also looks nicer.
