We haven't done any backmerge for a while due to the merge window, and it
starts to become an issue for komeda. Let's bring 5.4-rc1 in.

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.

When refactoring port lookup for DSS outputs, commit d17eb4537a7e
("drm/omap: Factor out common init/cleanup code for output devices")
incorrectly hardcoded usage of DT port 0. This breaks operation for SDI
(which uses the DT port 1) and DPI outputs other than DPI0 (which are
not used in mainline DT sources).
Fix this by using the port number from the output omap_dss_device
of_ports field.

Hook up drm_panel support in the omapdrm driver. The change is
relatively simply as the way has been paved by drm_bridge support
already. In addition to looking up, attaching to and detaching from the
panel, we only need to add panel support in the connector .get_modes()
handler, take connector bus flags (set by the panel) into account, and
enable/disable the panel in the encoder enable/disable operations
handlers.

Hook up drm_bridge support in the omapdrm driver. Despite the recent
extensive preparation work, this is a rather intrusive change, as the
management of outputs needs to be adapted through the driver to handle
both omap_dss_device and drm_bridge.
Connector creation is skipped when using a drm_bridge, as the bridge
creates the connector internally. This creates issues with systems that
split connector operations (such as modes retrieval and hot-plug
detection) across different bridges. These systems can't be supported
using drm_bridge for now (their support through the omap_dss_device
infrastructure is not affected), this will be fixed in subsequent
changes.

The omap_dss_device type and output_type fields differ mostly for
historical reasons. The output_type field is required for all devices
but the display at the end of the pipeline, and must be set to
OMAP_DISPLAY_TYPE_NONE for the latter. The type field is required for
all devices but the internal encoder, for which it is ignored.
The only reason why the output_type field must be set to
OMAP_DISPLAY_TYPE_NONE for the display at the end of the pipeline is to
identify omap_dss_device instances corresponding to displays. This is
not documented and confusing.
Clean the code by adding a new display field to the omap_dss_device
structure to identify displays, and merge the type and output_type
fields.

To simplify the pipeline disconnection handling merge the
omapdss_device_disconnect() and omapdss_output_unset_device() functions.
The device state check is now called for every device in the pipeline,
extending this sanity check coverage.
There is no need to return an error from omapdss_device_disconnect()
when the check fails, as omapdss_output_unset_device() used to do, given
that we can't prevent disconnection due to device unbinding (the return
value of omapdss_output_unset_device() is never checked in the current
code for that reason).

When a DSS output is (dis)connected the omapdss_output_(un)set_device()
function performs a sanity check to ensure that the output isn't already
(dis)connected. The check is unnecessary as those situations should
never happen, but can nonetheless be useful to catch driver bugs. To
prepare for removal of the omapdss_output_(un)set_device() functions
move the connection check to the omapdss_device_connect() function. The
omapdss_device_disconnect() already contains a corresponding check.

The omapdss_find_output_from_display() function is only used to retrieve
the dispc channel corresponding to the display. Return the dispc channel
directly, and rename the function to omapdss_device_get_dispc_channel()
to match its new purpose.
The dssdev->id check is removed as the dssdev is guaranteed to be an
output and have a non-zero id, as proved by the lack of crash despite
the caller never checking the returned pointer before dereferencing it.
As the function is not specific to outputs anymore, move it from
output.c to base.c.

The omap_dss_find_output_by_port_node() function defined in output.c
looks up an output from its port node. To do so it needs to call helper
functions from dss-of.c to lookup the port parent and the port number.
As omap_dss_find_output_by_port_node() is only called by
omapdss_of_find_source_for_first_ep() from dss-of.c this goes back and
forth between the to source files and isn't very clear.
Simplify the code by passing both the parent and the port number to
omap_dss_find_output_by_port_node() instead of the port node, and rename
the function to omap_dss_find_output_by_port().

The dss_mgr_ops operations implemented by the omapdrm side have to look
up the omap_crtc objects from global variables as they are only passed a
channel number. In order to remove global variables in the omapdrm
driver pass the omap_drm_private pointer to the dss_mgr_ops. This
requires storing a pointer to the omap_drm_private in a global variable
on the DSS side as a temporary measure until the omapdrm and omapdss
drivers get merged.
