Starting with DPCD version 2.0 bits 6:3 of the DP_DSC_BITS_PER_PIXEL_INC
DPCD register contains the NativeYCbCr422_MAX_bpp_DELTA field, which can
be non-zero as opposed to earlier DPCD versions, hence decoding the
bit_per_pixel increment value at bits 2:0 in the same register requires
applying a mask, do so.

The header drm_print.h uses members of struct drm_device pointers, as
such, it should include drm_device.h to let the compiler know the full
type definition.
Without such include, users of drm_print.h that don't explicitly need
drm_device.h would bump into build errors and be forced to include the
latter.

cgroup resource allocation has to be handled in TTM, so -EAGAIN from
cgroups can be converted into -ENOSPC, and the limitcg can be properly
evicted in ttm code.
When hitting a resource limit through -EAGAIN, the cgroup for which the
limit is hit is also returned. This allows eviction to delete only from
cgroups which are a subgroup of the current cgroup.
The returned CSS is used to determine if eviction is valuable for a
given resource, and allows TTM to only target specific resources to
lower memory usage.

The struct drm_dp_mst_topology_mgr *mgr parameter is only used for debug
logging in case the passed in link rate or lane count are zero. There's
no further error checking as such, and the function returns 0.
There should be no case where the parameters are zero. The returned
value is generally used as a divisor, and if we were hitting this, we'd
be seeing division by zero.
Just remove the debug logging altogether, along with the mgr parameter,
so that the function can be used in non-MST contexts without the
topology manager.
v2: Also remove drm_dp_mst_helper_tests_init as unnecessary (Imre)

The HDMI Connectors need to perform a variety of tasks when the HDMI
connector state changes. Such tasks include setting or invalidating CEC
address, notifying HDMI codec driver, updating scrambler data, etc.
Implementing such tasks in a driver-specific callbacks is error prone.
Start implementing the generic helper function (currently handling only
the HDMI Codec framework) to be used by drivers utilizing HDMI Connector
framework.

Add necessary glue code to be able to use new HDMI codec framework from
the DRM bridge drivers. The drm_bridge implements a limited set of the
hdmi_codec_ops interface, with the functions accepting both
drm_connector and drm_bridge instead of just a generic void pointer.
This framework is integrated with the DRM HDMI Connector framework, but
can also be used for DisplayPort connectors.

When memory stats is generated fresh everytime by going though all the
BOs, their active information is quite easy to get. But if the stats are
tracked with BO's state this becomes harder since the job scheduling
part doesn't really deal with individual buffers.

Atm when the connector is added to the drm_mode_config::connector_list,
the connector may not be fully initialized yet. This is not a problem
for static connectors initialized/added during driver loading, for which
the driver ensures that look-ups via the above list are not possible
until all the connector and other required state is fully initialized
already. It's also not a problem for user space looking up either a
static or dynamic (see what this is below) connector, since this will be
only possible once the connector is registered.
A dynamic - atm only a DP MST - connector can be initialized and added
after the load time initialization is done. Such a connector may be
looked up by in-kernel users once it's added to the connector list. In
particular a hotplug handler could perform a detection on all the
connectors on the list and hence find a connector there which isn't yet
initialized. For instance the connector's helper hooks may be unset,
leading to a NULL dereference while the detect helper calls the
connector's drm_connector_helper_funcs::detect() or detect_ctx()
handler.
To resolve the above issue, add a way for dynamic connectors to
separately initialize the DRM core specific parts of the connector
without adding it to the connector list - by calling the new
drm_connector_dynamic_init() - and to add the connector to the list
later once all the initialization is complete and the connector is
registered - by calling the new drm_connector_dynamic_register().
Adding the above 2 functions was also motivated to make the distinction
of the interface between static and dynamic connectors clearer: Drivers
should manually initialize and register only dynamic connectors (with
the above 2 functions). A driver should only initialize a static
connector (with one of the drm_connector_init*, drmm_connector_init*
functions) while the registration of the connector will be done
automatically by DRM core.
v2: (Jani)
- Let initing DDC as well via drm_connector_init_core().
- Rename __drm_connector_init to drm_connector_init_core_and_add().
v3:
- Rename drm_connector_init_core() to drm_connector_dynamic_init().
(Sima)
- Instead of exporting drm_connector_add(), move adding the connector
to the registration step via a new drm_connector_dynamic_register().
(Sima)
- Update drm_connector_dynamic_init()'s function documentation and the
commit log according to the above changes.
- Update the commit log describing the problematic scenario during
connector detection. (Maxime)

The connector->eld is accessed by the .get_eld() callback. This access
can collide with the drm_edid_to_eld() updating the data at the same
time. Add drm_connector.eld_mutex to protect the data from concurrenct
access. Individual drivers are not updated (to reduce possible issues
while applying the patch), maintainers are to find a best suitable way
to lock that mutex while accessing the ELD data.

Add a Synopsys Designware MIPI DSI host DRM bridge driver for their
DSI2 host controller, based on the Rockchip version from the driver
rockchip/dw-mipi-dsi2.c in their vendor-kernel with phy & bridge APIs.
While the driver is heavily modelled after the previous IP, the register
set of this DSI2 controller is completely different and there are also
additional properties like the variable-width phy interface.

If the MST topology is removed during the reception of an MST down reply
or MST up request sideband message, the
drm_dp_mst_topology_mgr::up_req_recv/down_rep_recv states could be reset
from one thread via drm_dp_mst_topology_mgr_set_mst(false), racing with
the reading/parsing of the message from another thread via
drm_dp_mst_handle_down_rep() or drm_dp_mst_handle_up_req(). The race is
possible since the reader/parser doesn't hold any lock while accessing
the reception state. This in turn can lead to a memory corruption in the
reader/parser as described by commit bd2fccac61b4 ("drm/dp_mst: Fix MST
sideband message body length check").
Fix the above by resetting the message reception state if needed before
reading/parsing a message. Another solution would be to hold the
drm_dp_mst_topology_mgr::lock for the whole duration of the message
reception/parsing in drm_dp_mst_handle_down_rep() and
drm_dp_mst_handle_up_req(), however this would require a bigger change.
Since the fix is also needed for stable, opting for the simpler solution
in this patch.

Panels using a PWM-controlled backlight source do not have a standard
way to communicate their valid PWM ranges.
On x86 the ranges are read from ACPI through driver-specific tables.
The built-in ranges are not necessarily correct, or may grow stale if an
older device can be retrofitted with newer panels.
Add a quirk infrastructure with which the minimum valid backlight value
can be maintained as part of the kernel.

All MTL and ARL SKUs share the same GSC FW, but the newer platforms are
only supported in newer blobs. In particular, ARL-S is supported
starting from 102.0.10.1878 (which is already the minimum required
version for ARL in the code), while ARL-H and ARL-U are supported from
102.1.15.1926. Therefore, the driver needs to check which specific ARL
subplatform its running on when verifying that the GSC FW is new enough
for it.
