1ed3d2567c drm/amdgpu: keep the MMU lock until the update ends v4

aa4ec7ce7e drm/amdgpu: revert "fix deadlock of reservation between cs and gpu reset v2"
This reverts commit 10e709cb29.

The patch doesn't work at all:
1. The CS can still be blocked because of amdgpu_ctx_add_fence().
2. The order of submission isn't correct any more.
3. We could end up using freed up memory because we now drop the
   ctx reference to early.

This needs to be fixed cleanly by doing the context handling after the BO
handling, but this is a larger task just avoid the obvious crashes for now.

3164888a40 drm/i915: Increase poll time for BDW FCLK_DONE
During IGT testing it has been shown that the specification
defined polling time of 1 us for FCLK_DONE, is sometimes not
enough. The issue is still reproducible while disabling
C-states through the PM QoS framework and also while disabling
preemtion. From this the most plausible explanation is that the
issue is due to a firmware flaw.
As a workaround, it is better to wait a little bit longer for
the FCLK_DONE to come around, than to leave with an DRM_ERROR
and having FCLK_DONE at a randome time after.
While spinning a list of igt tests prone to reproduce the issue
the FCLK_DONE poll failed at approximately 2% of the invocations
of the bdw_set_cdclk function. The longest poll time during this
testing was measured to ~7us. So, the suggested new poll time of
100us is on the safe side.

v2: Added more documentation about investigations done.

b0e07da3f5 qxl: fix primary surface handling
The atomic conversion of the qxl driver didn't got the primary surface
handling completely right.  It works in the common simple cases, but
fails for example when changing the display resolution using xrandr or
in multihead setups.

The rules are simple:  There is one primary surface.  Before defining a
new one you have to destroy the old one.

This patch makes qxl_primary_atomic_update() destroy the primary surface
before defining a new one.  It fixes is_primary flag updates.  It adds
is_primary checks so we don't try to update the primary surface in case
it already has the state we want it being in.

ed63d24b4d drm/i915/psr: hsw_psr_activate.
On HSW+ the real activate of PSR is decided by the source
after certain amount of configured idle frames.

However for the driver perspective where we track psr.active
variable this function here is the actual activate one. So
let's rename it before moving to vfunc with that.

v2: Fix typo on commit message (DK).

424644c250 drm/i915/psr: vfunc for disabling source.
VLV/CHV has a total different PSR implementation than the
other platforms, so let's start moving that to vfuncs.
Let's start with disable_src one.

v2: Rebased on top of commit d2419ffc10 ("drm/i915: Plumb
    crtc_state to PSR enable/disable")

0f328da611 drm/i915/psr: Avoid any PSR stuff on platforms without support.
We really don't want to setup vfuncs and lock mutexes on
platforms that has no support to PSR.

Also we know what platforms they are so let's do it quietly.

9ab12e88a0 drm/tve200: Clean up panel bridging
This makes use of the drm_simple_display_pipe_attach_bridge()
call and removes the two calls removing the bridge, which were
erroneous: they unregister the bridge which is not what
we want, we just want to unreference it and that is already
handled by the core.

0bb9c2b27f drm/dp/mst: Sideband message transaction to power up/down nodes
The POWER_DOWN_PHY and POWER_UP_PHY sideband message transactions allow
the source to reqest any node in a mst path or a whole path to be
powered down or up. This allows drivers to target a specific sink in the
MST topology, an improvement over just power managing the imediate
downstream device. Secondly, since the request-reply protocol waits for an
ACK, we can be sure that a downstream sink has enough time to respond to a
power up/down request.
