tda998x_edid_read() returns a const struct drm_edid pointer, but when
tda998x_edid_delay_wait() fails (process killed while waiting for the
HPD timeout), the integer literal 0 is returned instead of NULL,
triggering a sparse warning: "Using plain integer as NULL pointer"
Replace 0 with NULL to fix the sparse warning.

of_get_property() returns a pointer to big-endian (__be32) data, but
port_data in tda998x_get_audio_ports() was declared as const u32 *,
causing a sparse endianness type mismatch warning. Fix the declaration
to use const __be32 *.

the bridge stayed registered without drm_bridge_remove(), leaking the

In analogix_dp_link_start(), &link_train.training_lane[] is used to

DP_TRAINING_LANEx_SET, which can remove the redundant assignments
and make codes more concise.

The hdmi_colorspace enum was defined to represent the colorspace value
of the HDMI infoframes. It was later used by some HDMI drivers to
express the output format they should be setting up.
During the introduction of the HDMI helpers, it then was used to
represent it in the drm_connector_hdmi_state structure.
However, it's always been somewhat redundant with the DRM_COLOR_FORMAT_*
defines, and now with the drm_output_color_format enum. Let's
consolidate around drm_output_color_format in drm_connector_hdmi_state
to facilitate the current effort to provide a global output format
selection mechanism.

Now that we introduced a new drm_output_color_format enum to represent
what DRM_COLOR_FORMAT_* bits were representing, we can switch to the new
enum.
The main difference is that while DRM_COLOR_FORMAT_ was a bitmask,
drm_output_color_format is a proper enum. However, the enum was done is
such a way than DRM_COLOR_FORMAT_X = BIT(DRM_OUTPUT_COLOR_FORMAT_X) so
the transitition is easier.
The only thing we need to consider is if the original code meant to use
that value as a bitmask, in which case we do need to keep the bit shift,
or as a discriminant in which case we don't.

Some rc device drivers have a race condition between rc_unregister_device()
and irq or urb callbacks. This is because rc_unregister_device() does two
things, it marks the device as unregistered so no new commands can be
issued and then it calls rc_free_device(). This means the driver has no
chance to cancel any pending urb callbacks or interrupts after the device
has been marked as unregistered. Those callbacks may access struct rc_dev
or its members (e.g. struct ir_raw_event_ctrl), which have been freed by
rc_free_device().
This change removes the implicit call to rc_free_device() from
rc_unregister_device(). This means that device drivers can call
rc_unregister_device() in their remove or disconnect function, then cancel
all the urbs and interrupts before explicitly calling rc_free_device().
Note this is an alternative fix for an issue found by Haotian Zhang, see
the Closes: tags.

setting up the Type-C port. At this point, when
anx7625_ocm_loading_check() checks if it can disable PD or not, it will
notice that typec_port is not set and disable PD, breaking orientation
and HPD handling. Unify the check between anx7625_ocm_loading_check()
anx7625_i2c_probe() and anx7625_typec_register() and check for the
presence of the "connector" node.

The typec_set_*() functions do not tolerate being passed the NULL
typec_port instance. However, if CONFIG_TYPEC is enabled, but anx7625
DT node doesn't have the usb-c connector fwnode, then typec_port remains
NULL, crashing the kernel. Prevent calling typec_set_foo() functions by
checking that ctx->typec_port is not NULL in anx7625_typec_set_status().

When CONFIG_TYPEC is enabled, but USB_ROLE_SWITCH=m, the anx7625 driver
fails to link as built-in:
aarch64-linux-ld: drivers/gpu/drm/bridge/analogix/anx7625.o: in function `anx7625_i2c_remove':
anx7625.c:(.text+0x6ec): undefined reference to `usb_role_switch_put'

anx7625.c:(.text+0x5368): undefined reference to `fwnode_usb_role_switch_get'
The problem is that both dependencies are optional in the sense of allowing
the anx7625 driver to call the exported interfaces to be used from a loadable
module, but cannot work for built-in drivers. It would be possible to handle
all nine combinations of the CONFIG_TYPEC and CONFIG_USB_ROLE_SWITCH tristate
options, but that does add a lot of complexity that seems unnecessary when
in reality any user of this driver would have both enabled anyway.
Turn both dependencies into hard 'depends on' here to only allow configurations
where it's possible to actually use them, and remove the misguided IS_REACHABLE()
check that did nothing here.

Dual LVDS output (available on the SN65DSI84) requires HSYNC_PULSE_WIDTH
and HORIZONTAL_BACK_PORCH to be divided by two with respect to the values
used for single LVDS output.
While not clearly stated in the datasheet, this is needed according to the
DSI Tuner [0] output. It also makes sense intuitively because in dual LVDS
output two pixels at a time are output and so the output clock is half of
the pixel clock.
Some dual-LVDS panels refuse to show any picture without this fix.
Divide by two HORIZONTAL_FRONT_PORCH too, even though this register is used
only for test pattern generation which is not currently implemented by this
driver.

The DSI frequency must be in the range:
(CHA_DSI_CLK_RANGE * 5 MHz) <= DSI freq < ((CHA_DSI_CLK_RANGE + 1) * 5 MHz)
So the register value should point to the lower range value, but
DIV_ROUND_UP() rounds the division to the higher range value, resulting in
an excess of 1 (unless the frequency is an exact multiple of 5 MHz).
For example for a 437100000 MHz clock CHA_DSI_CLK_RANGE should be 87 (0x57):
(87 * 5 = 435) <= 437.1 < (88 * 5 = 440)
but current code returns 88 (0x58).
Fix the computation by removing the DIV_ROUND_UP().

Reduce the log level for cdns_mhdp_dpcd_read and cdns_mhdp_dpcd_write
errors in cdns_mhdp_transfer function as in case of failure, there is
flooding of these prints along with other indicators like EDID failure
logs which are fairly intuitive in themselves rendering these error logs
useless.
Also, the caller functions for the cdns_mhdp_transfer in drm_dp_helper.c
(which calls it 32 times), has debug log level in case transfer fails.
So having a superseding log level in cdns_mhdp_transfer seems bad.

Now that we have dropped the legacy code which became redundant with
introduction of DRM_BRIDGE_ATTACH_NO_CONNECTOR
usecase in driver,we can cleanly switch to drm_connector pointer
instead of structure.
Rename the connector_ptr member variable to connector for clarity and
consistency. The driver was using both connector and connector_ptr members,
but connector_ptr was the only one actually used throughout the code.
This change removes the unused connector struct member and renames
connector_ptr to connector for better readability.
This is purely a code cleanup change with no functional impact. All
references to connector_ptr are updated to use the renamed connector
variable throughout the driver.

Parse the data lane count out of DT. Limit the supported data lanes
to 1..4 which is the maximum available DSI pairs on the connector of
any known panels which may use this bridge. Internally, this bridge
is an ChipOne ICN6211 which loads its register configuration from a
dedicated storage and its I2C does not seem to be accessible. The
ICN6211 also supports up to 4 DSI lanes, so this is a hard limit.
To avoid any breakage on old DTs where the parsing of data lanes from
DT may fail, fall back to the original hard-coded value of 2 lanes and
warn user.
The lane configuration is preconfigured in the bridge for each of the
WaveShare panels. The 13.3" DSI panel works with 4-lane configuration,
others seem to use 2-lane configuration. This is a hardware property,
so the actual count should come from DT.

In order to avoid any probe ordering issue, the best practice is to move
the secondary MIPI-DSI device registration and attachment to the
MIPI-DSI host at probe time.
Besides solving the probe ordering problems, this makes the bridge work
with R-Car DU. The R-Car DU will attempt to locate the DSI host bridge in
its own rcar_du_probe()->rcar_du_modeset_init()->rcar_du_encoder_init()
by calling of_drm_find_bridge() which calls of_drm_find_and_get_bridge()
and iterates over bridge_list to locate the DSI host bridge.
However, unless the WS driver calls mipi_dsi_attach() in probe(), the
DSI host bridge .attach callback rcar_mipi_dsi_host_attach() is not
called and the DSI host bridge is not added into bridge_list. Therefore
the of_drm_find_and_get_bridge() called from du_probe() will never find
the DSI host bridge and probe will indefinitelly fail with -EPROBE_DEFER.
The circular dependency here is, that if rcar_du_encoder_init() would
manage to find the DSI host bridge, it would call the WS driver .attach
callback ws_bridge_bridge_attach(), but this is too late and can never
happen. This change avoids the circular dependency.

This driver obtains a bridge pointer from of_drm_find_bridge() in the probe
function and stores it until driver removal. of_drm_find_bridge() is
deprecated, so move to of_drm_find_and_get_bridge() for the bridge to be
refcounted and use bridge->next_bridge to put the reference on
deallocation.
To keep the code as simple and reliable as possible remove the intermediate
next_bridge and selected_bridge variables.
Get/put operations on the remaining pointer is pl->bridge.next_bridge,
which is tied to the struct imx8qxp_pixel_link lifetime, are:
- get reference when assigned (by of_drm_find_and_get_bridge())
- put reference before reassignment if reassignment happens
- put reference when the struct imx8qxp_pixel_link embedding the
struct drm_bridge is destroyed (struct drm_bridge::next_bridge)

This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate

without removing the bridge, causing a memory leak.
Fix this by adding proper error handling with goto labels to ensure
drm_bridge_remove() is called in all error paths. Also ensure that
samsung_dsim_unregister_te_irq() is called if the attach operation
fails after the TE IRQ has been registered.
samsung_dsim_unregister_te_irq() function is moved without changes
to be before samsung_dsim_host_attach() to avoid forward declaration.

Return the value of devm_drm_bridge_add() in order to propagate the
error properly, if it fails due to resource allocation failure or bridge
registration failure.
This ensures that the bind function fails safely rather than proceeding
with a potentially incomplete bridge setup.
