96591a4b93 drm: bridge: dw-hdmi: Pass private data pointer to .mode_valid()
Platform glue drivers for dw_hdmi may need to access device-specific
data from their .mode_valid() implementation. They currently have no
clean way to do so, and one driver hacks around it by accessing the
dev_private data of the drm_device retrieved from the connector.

Add a priv_data void pointer to the dw_hdmi_plat_data structure, and
pass it to the .mode_valid() function.

Create GEM objects with drm_gem_cma_create_object_default_funcs(), which
allocates the object and sets CMA's default object functions. Corresponding

Driver and object-function instances use the same callback functions, with

b570e88d88 drm/rcar-du: Drop explicit drm_mode_config_cleanup call
It's right above the drm_dev_put().

This is made possible by a preceeding patch which added a drmm_
cleanup action to drm_mode_config_init(), hence all we need to do to
ensure that drm_mode_config_cleanup() is run on final drm_device
cleanup is check the new error code for _init().

Aside: Another driver with a bit much devm_kzalloc, which should
probably use drmm_kzalloc instead ...

v2: Explain why this cleanup is possible (Laurent).

v3: Use drmm_mode_config_init() for more clarity (Sam, Thomas)

a25b988ff8 drm/bridge: Extend bridge API to disable connector creation
Most bridge drivers create a DRM connector to model the connector at the
output of the bridge. This model is historical and has worked pretty
well so far, but causes several issues:

- It prevents supporting more complex display pipelines where DRM
connector operations are split over multiple components. For instance a
pipeline with a bridge connected to the DDC signals to read EDID data,
and another one connected to the HPD signal to detect connection and
disconnection, will not be possible to support through this model.

- It requires every bridge driver to implement similar connector
handling code, resulting in code duplication.

- It assumes that a bridge will either be wired to a connector or to
another bridge, but doesn't support bridges that can be used in both
positions very well (although there is some ad-hoc support for this in
the analogix_dp bridge driver).

In order to solve these issues, ownership of the connector should be
moved to the display controller driver (where it can be implemented
using helpers provided by the core).

Extend the bridge API to allow disabling connector creation in bridge
drivers as a first step towards the new model. The new flags argument to
the bridge .attach() operation allows instructing the bridge driver to
skip creating a connector. Unconditionally set the new flags argument to
0 for now to keep the existing behaviour, and modify all existing bridge
drivers to return an error when connector creation is not requested as
they don't support this feature yet.

The change is based on the following semantic patch, with manual review
and edits.

59c1f061c9 drm: rcar-du: lvds: Allow for even and odd pixels swap
DT properties dual-lvds-even-pixels and dual-lvds-odd-pixels
can be used to work out if the driver needs to swap even
and odd pixels around.

This patch makes use of the return value from function
drm_of_lvds_get_dual_link_pixel_order to determine if we
need to swap odd and even pixels around for things to work
properly.

The dual_link boolean field from struct rcar_lvds is not
sufficient to describe the type of LVDS link anymore, since
we now have information related to pixel order, therefore
rename it to link_type and repurpose its usage to fit the
new requirements.

593885b085 drm: rcar-du: lvds: Get mode from state
The R-Car LVDS encoder driver implements the bridge .mode_set()
operation for the sole purpose of storing the mode in the LVDS private
data, to be used later when enabling the encoder.

Switch to the bridge .atomic_enable() and .atomic_disable() operations
in order to access the global atomic state, and get the mode from the
state instead. Remove both the unneeded .mode_set() operation and the
display_mode and mode fields storing state data from the rcar_lvds
private structure.

As a side effect we get the CRTC from the state, replace the CRTC
pointer retrieved through the bridge's encoder that shouldn't be used by
atomic drivers.

While at it, clarify a few error messages in rcar_lvds_get_lvds_mode()
and turn them into warnings as they are not fatal.

35a61fe921 drm: Stop accessing encoder->bridge directly
We are about to replace the single-linked bridge list by a double-linked
one based on list.h, leading to the suppression of the encoder->bridge
field. But before we can do that we must provide a
drm_bridge_chain_get_first_bridge() bridge helper and patch all drivers
and core helpers to use it instead of directly accessing encoder->bridge.

Note that we still have 2 drivers (VC4 and Exynos) manipulating the
encoder->bridge field directly because they need to cut the bridge chain
in order to control the enable/disable sequence. This is definitely
not something we want to encourage, so let's keep those 2 oddities
around until we find a better solution.

3986457110 drm: rcar_lvds: Fix color mismatches on R-Car H2 ES2.0 and later
Commit 5cca30ebe0 ("drm/rcar-du: Add LVDS_LANES quirk") states
that LVDS lanes 1 and 3 are inverted on R-Car H2 ES1 only, and that the
problem has been fixed in newer revisions.

However, the code didn't take into account the actual hardware revision,
thus applying the quirk also on newer hardware revisions, causing green
color reversals.

Fix this by applying the quirk when running on R-Car H2 ES1.x only.

89958b7cd9 drm/bridge: panel: Infer connector type from panel by default
The drm panel bridge creates a connector using a connector type
explicitly passed by the display controller or bridge driver that
instantiates the panel bridge. Now that drm_panel reports its connector
type, we can use it to avoid passing an explicit (and often incorrect)
connector type to drm_panel_bridge_add() and
devm_drm_panel_bridge_add().

Several drivers report incorrect or unknown connector types to
userspace. Reporting a different type may result in a breakage. For that
reason, rename (devm_)drm_panel_bridge_add() to
(devm_)drm_panel_bridge_add_typed(), and add new
(devm_)drm_panel_bridge_add() functions that use the panel connector
type. Update all callers of (devm_)drm_panel_bridge_add() to the _typed
function, they will be converted one by one after testing.

The panel drivers have been updated with the following Coccinelle
semantic patch, with manual inspection and fixes to indentation.

@@
expression bridge;
expression dev;
expression panel;
identifier type;
@@
(
-bridge = drm_panel_bridge_add(panel, type);
+bridge = drm_panel_bridge_add_typed(panel, type);
|
-bridge = devm_drm_panel_bridge_add(dev, panel, type);
+bridge = devm_drm_panel_bridge_add_typed(dev, panel, type);

ee68c743f8 drm: Stop including drm_bridge.h from drm_crtc.h
We are about to add a drm_bridge_state that inherits from
drm_private_state which is defined in drm_atomic.h. Problem is,
drm_atomic.h includes drm_crtc.h which in turn includes drm_bridge.h,
leading to "drm_private_state has incomplete type" error.

Let's force all users of the drm_bridge API to explicitly include
drm_bridge.h.

a53358a31c drm: rcar_lvds: Fix dual link mode operations
The R-Car LVDS encoder units support dual-link operations by splitting
the pixel output between the primary encoder and the companion encoder.

Currently the companion encoder fails at probe time, causing the
registration of the primary to fail as well, preventing the whole DU unit
from being registered at all.

Fix this by not bailing out from probe with error if the
"renesas,companion" property is not specified.

Split out to make the functional changes stick out more.

All places where DRIVER_PRIME was used have been removed in previous

v2: amdgpu gained DRIVER_SYNCOBJ_TIMELINE.

v3: amdgpu lost DRIVER_SYNCOBJ_TIMELINE.

v4: Don't add a space in i915_drv.c (Sam)

v5: Add note that previous patches removed all the DRIVER_PRIME users
already (Emil).

v6: Fixupe ingenic (new driver) while applying.

6f3b62781b drm: Convert connector_helper_funcs->atomic_check to accept drm_atomic_state
Everyone who implements connector_helper_funcs->atomic_check reaches
into the connector state to get the atomic state. Instead of continuing
this pattern, change the callback signature to just give atomic state
and let the driver determine what it does and does not need from it.

Eventually all atomic functions should do this, but that's just too much
busy work for me.

Changes in v3:
- Added to the set
Changes in v4:
- None
Changes in v5:
- intel_digital_connector_atomic_check declaration moved to i915_atomic.h
