drm: rcar-du: Set primary plane zpos immutably at initializing

According to drm_plane_create_zpos_property() function documentation,
all planes zpos range should be set if zpos property is supported.
However, the rcar-du driver didn't set primary plane zpos range. Since
the primary plane's zpos is fixed, set it immutably.

While the property is not mandatory for drivers to implement, mixing

drm/amd/display: Fix vblank and pageflip event handling for FreeSync

[Why]
We're sending the drm vblank event a frame too early in the case where
the pageflip happens close to VUPDATE and ends up blocking the signal.

The implementation in DM was previously correct *before* we started
sending vblank events from VSTARTUP unconditionally to handle cases
where HUBP was off, OTG was ON and userspace was still requesting some
DRM planes enabled. As part of that patch series we dropped VUPDATE
since it was deemed close enough to VSTARTUP, but there's a key
difference betweeen VSTARTUP and VUPDATE - the VUPDATE signal can be
blocked if we're holding the pipe lock.

There was a fix recently to revert the unconditional behavior for the
DCN VSTARTUP vblank event since it was sending the pageflip event on
the wrong frame - once again, due to blocking VUPDATE and having the
address start scanning out two frames later.

The problem with this fix is it didn't update the logic that calls
drm_crtc_handle_vblank(), so the timestamps are totally bogus now.

[How]
Essentially reverts most of the original VSTARTUP series but retains
the behavior to send back events when active planes == 0.

Some refactoring/cleanup was done to not have duplicated code in both
the handlers.

drm/amd/display: add addition dc type to translate to dmub fw type

[Why]
For a type like PSR version, it makes sense for most of the code
to include a dc type, instead of having this a fw type define since
this is a capability and type exposed by dc.

Especially if it doesn't even need to communicate with the fw.

The code that is packing the firmware command message
should be the one who needs to translate the psr version
into a command that the firmware understands.

[How]
Add a dc_psr_version enum.

drm/mm: optimize rb_hole_addr rbtree search

Userspace can severely fragment rb_hole_addr rbtree by manipulating
alignment while allocating buffers. Fragmented rb_hole_addr rbtree
would result in large delays while allocating buffer object for a
userspace application. It takes long time to find suitable hole
because if we fail to find a suitable hole in the first attempt
then we look for neighbouring nodes using rb_prev()/rb_next().
Traversing rbtree using rb_prev()/rb_next() can take really long
time if the tree is fragmented.

This patch improves searches in fragmented rb_hole_addr rbtree by
modifying it to an augmented rbtree which will store an extra field
in drm_mm_node, subtree_max_hole. Each drm_mm_node now stores maximum
hole size for its subtree in drm_mm_node->subtree_max_hole. Using
drm_mm_node->subtree_max_hole, it is possible to eliminate a complete
subtree if that subtree is unable to serve a request hence reducing
number of rb_prev()/rb_next() used.

With this patch applied, 1 million bo allocs on amdgpu took ~8 sec,
compared to 50k bo allocs which took 28 sec without it.

drm/bridge: chrontel-ch7033: Add a new driver

This is a driver for video encoder with VGA and DVI/HDMI outputs.

There is no documentation for the chip -- the operation was guessed from
what was sniffed on a Dell Wyse 3020 ThinOS terminal, the register names
come from the ch7035 driver in Mediatek's GPL code dump.

Only bare minimum is implemented -- no fancy stuff, such as scaling. That
would only worsen our misery. We don't load the firmware and we don't need
to even bother enabling the MCU.  There are probably no distributable
firmware images anyway.

Tested with a handful of monitors ranging from 1024x768@75 to 1400x1050@60,
with VGA as well as DVI.

drm/tidss: remove AM65x PG1 YUV erratum code

AM65x PG1 has a HW issue with YUV pixel formats, resulting in wrong
colors on the screen. This issue is fixed in PG2 hardware.

The driver currently has code to hide YUV pixel formats from the
userspace. To support PG2, we would need to add code to detect the SoC
version and hide the YUV formats based on that.

However, as PG1 will be phased out and PG2 will be the main platform, a
much simpler solution is just to drop the code in question. The downside
is that the users will be able to use YUV formats on PG1, getting wrong
colors on the screen. On the other hand, that may also be a plus, as the
same applications will now work on PG1 and PG2, even if the colors are
wrong on PG1.

drm/omap: change default signal polarities and drives

If the given videomode does not specify DISPLAY_FLAG_* for the specific
signal property, the driver used a default value. These defaults were
never thought through, as the expectation was that all the DISPLAY_FLAGS
are always set explicitly.

With DRM bridge and panel drivers this is not the case, and while that
issue should be resolved in the future, it's still good to have sane
signal defaults.

This patch changes the defaults to what the hardware has as reset
defaults. Also, based on my experience, I think they make sense and are
more likely correct than the defaults without this patch.
