Add new struct drm_device based WARN* macros. These are modeled after
the core kernel device based WARN* macros. These would be preferred
over the regular WARN* macros, where possible.
These macros include device information in the backtrace, so we know
what device the warnings originate from.
Knowing the device specific information in the backtrace would be
helpful in development all around.

If the resolution of the TFT display is smaller than the maximum
resolution supported by the display controller, the display may be
connected to the driver output arrays with a horizontal and/or vertical
offset, leading to a shifted image.
Add support for specifying these offsets.

[Why]
Noticed this while testing MST with the 4 ports MST hub from
StarTech.com. Sometimes can't light up monitors normally and get the
error message as 'sideband msg build failed'.
Look into aux transactions, found out that source sometimes will send
out another down request before receiving the down reply of the
previous down request. On the other hand, in drm_dp_get_one_sb_msg(),
current code doesn't handle the interleaved replies case. Hence, source
can't build up message completely and can't light up monitors.
[How]
For good compatibility, enforce source to send out one down request at a
time. Add a flag, is_waiting_for_dwn_reply, to determine if the source
can send out a down request immediately or not.
- Check the flag before calling process_single_down_tx_qlock to send out
a msg
- Set the flag when successfully send out a down request
- Clear the flag when successfully build up a down reply
- Clear the flag when find erros during sending out a down request
- Clear the flag when find errors during building up a down reply
- Clear the flag when timeout occurs during waiting for a down reply
- Use drm_dp_mst_kick_tx() to try to send another down request in queue
at the end of drm_dp_mst_wait_tx_reply() (attempt to send out messages
in queue when errors occur)

Making this IS_REACHABLE() was still wrong, as that just determines
whether the lower-level backlight code would be reachable from the panel
driver. However, with CONFIG_DRM=y and CONFIG_BACKLIGHT_CLASS_DEVICE=m,
the drm_panel_of_backlight is left out of drm_panel.o but the condition
tells the driver that it is there, leading to multiple link errors such as

Not every platform needs quirk detection for panel orientation, so
split the drm_connector_init_panel_orientation_property into two
functions. One for platforms without the need for quirks, and the
other for platforms that need quirks.
Hans de Goede (changes in v2):
Rename the function from drm_connector_init_panel_orientation_property
to drm_connector_set_panel_orientation[_with_quirk] and pass in the
panel-orientation to set.
Beside the rename, also make the function set the passed in value
only once, if the value was set before (to a value other then
DRM_MODE_PANEL_ORIENTATION_UNKNOWN) make any further set calls a no-op.
This change is preparation for allowing the user to override the
panel-orientation for any connector from the kernel commandline.
When the panel-orientation is overridden this way, then we must ignore
the panel-orientation detection done by the driver.

For DSC case we cannot use topology manager's PBN divider
variable. The default divider does not take FEC into account.
Therefore the driver has to calculate its own divider based

zero, otherwise default topology manager's pbn_div will be used.

drm_bridge_state is extended to describe the input and output bus
configurations. These bus configurations are exposed through the
drm_bus_cfg struct which encodes the configuration of a physical
bus between two components in an output pipeline, usually between
two bridges, an encoder and a bridge, or a bridge and a connector.
The bus configuration is stored in drm_bridge_state separately for
the input and output buses, as seen from the point of view of each
bridge. The bus configuration of a bridge output is usually identical
to the configuration of the next bridge's input, but may differ if
the signals are modified between the two bridges, for instance by an
inverter on the board. The input and output configurations of a
bridge may differ if the bridge modifies the signals internally,
for instance by performing format conversion, or*modifying signals
polarities.
Bus format negotiation is automated by the core, drivers just have
to implement the ->atomic_get_{output,input}_bus_fmts() hooks if they
want to take part to this negotiation. Negotiation happens in reverse
order, starting from the last element of the chain (the one directly
connected to the display) up to the first element of the chain (the one
connected to the encoder).
During this negotiation all supported formats are tested until we find
one that works, meaning that the formats array should be in decreasing
preference order (assuming the driver has a preference order).
Note that the bus format negotiation works even if some elements in the
chain don't implement the ->atomic_get_{output,input}_bus_fmts() hooks.
In that case, the core advertises only MEDIA_BUS_FMT_FIXED and lets
the previous bridge element decide what to do (most of the time, bridge
drivers will pick a default bus format or extract this piece of
information from somewhere else, like a FW property).

So that bridge drivers have a way to check/reject an atomic operation.
The drm_atomic_bridge_chain_check() (which is just a wrapper around
the ->atomic_check() hook) is called in place of
drm_bridge_chain_mode_fixup() (when ->atomic_check() is not implemented,
the core falls back on ->mode_fixup(), so the behavior should stay
the same for existing bridge drivers).

One of the last remaining objects to not have its atomic state.
This is being motivated by our attempt to support runtime bus-format
negotiation between elements of the bridge chain.
This patch just paves the road for such a feature by adding a new
drm_bridge_state object inheriting from drm_private_obj so we can
re-use some of the existing state initialization/tracking logic.

Adding the pitch alignment as an argument to
drm_gem_vram_fill_create_dumb() allows to align scanlines to certain
offsets. A value of 0 disables scanline pitches.
v3:
* only do power-of-2 test if pitch_align given; fails otherwise
* mgag200: call drm_gem_vram_fill_create_dumb() with pitch_align
v2:
* split of patch from related hibmc changes
* test if scanline pitch is power of 2

Annoyingly __drm_atomic_helper_crtc_reset() does two
totally separate things:
a) reset the state to defaults values
b) assign the crtc->state pointer
I just want a) without the b) so let's split out part
a) into __drm_atomic_helper_crtc_state_reset(). And
of course we'll do the same thing for planes and connectors.

An LVDS dual-link connection is made of two links, with even
pixels transitting on one link, and odd pixels on the other
link. The device tree can be used to fully describe dual-link
LVDS connections between encoders and bridges/panels.
The sink of an LVDS dual-link connection is made of two ports,
the corresponding OF graph port nodes can be marked
with either dual-lvds-even-pixels or dual-lvds-odd-pixels,
and that fully describes an LVDS dual-link connection,
including pixel order.
drm_of_lvds_get_dual_link_pixel_order is a new helper
added by this patch, given the source port nodes it
returns DRM_LVDS_DUAL_LINK_EVEN_ODD_PIXELS if the source
port nodes belong to an LVDS dual-link connection, with even
pixels expected to be generated from the first port, and odd
pixels expected to be generated from the second port.
If the new helper returns DRM_LVDS_DUAL_LINK_ODD_EVEN_PIXELS,
odd pixels are expected to be generated from the first port,
and even pixels from the other port.

The initial commit followed by the fix didn't
take into consideration the case:
CONFIG_DRM_PANEL=y
CONFIG_BACKLIGHT_CLASS_DEVICE=m
CONFIG_DRM_I915=y
where symbol devm_of_find_backlight() is not reachable from DRM subsystem.
Quick fix is to avoid drm_panel_of_backlight() from exporting in such case.
