There was a lot of conflicts this round between fixes and next,
and I'd like to get the merge resolutions that we have in drm-tip.

ps8640_aux_transfer_msg() programs the AUX address registers, starts the
AUX transfer, waits for SWAUX_SEND to clear, and reads the AUX status
register. Several of those regmap operations have return values, but the
function only checks a stale ret after the status read.
Propagate failures from the address write, transfer start, completion
poll, and status read. This avoids returning a transfer length when the
bridge register transaction or AUX completion wait failed.

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.
The mentioned robustness is relevant for a planned change to struct
i2c_device_id that replaces .driver_data by an anonymous union.
While touching all these arrays, unify usage of whitespace in the list
terminator and drop trailing commas there.
This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

If the probe function returns an error after getting the I2C adapter for
DDC, the reference to the adapter is never released. Fix it by releasing
it in the bridge .destroy() handler.
There is no need to test the ddc pointer with !IS_ERR(), as
of_get_i2c_adapter_by_node() returns NULL on error.

Callers of of_drm_find_panel() and drm_of_find_panel_or_bridge()
receive a pointer with no reference held, creating a window where
the panel device can be unregistered and freed between the lookup
and first use (e.g., drm_panel_prepare()).
Fix the lookup function by acquiring a reference with drm_panel_get()
before returning, under panel_lock. Callers are now responsible for
calling drm_panel_put() when they no longer need the pointer.
For bridge drivers that immediately wrap the panel in a panel_bridge
(which acquires its own reference), release the lookup reference right
after the bridge creation call.
For analogix-anx6345, which stores the panel for direct use, release
the reference in the i2c remove path.
For platform drivers using analogix_dp_core with a component lifecycle
(exynos_dp, rockchip analogix_dp), release the lookup reference in the
platform remove() function. The panel_bridge created during bind() holds
a separate reference that devm cleanup releases after remove() returns.
Also fix devm_drm_of_get_bridge() and drmm_of_get_bridge() in
bridge/panel.c itself, update a second batch of drivers calling
of_drm_find_panel() or drm_of_find_panel_or_bridge() to release the
lookup reference after wrapping the panel in a bridge, and handle the
cases where a panel is found but cannot be used, dropping the reference
immediately in those paths.

drm_panel_bridge_add_typed() stores a pointer to the drm_panel it
wraps, but never acquires a reference to it. If the panel device
goes away while a panel_bridge still exists, the dangling pointer can
be dereferenced through panel_bridge->panel.
Acquire a reference in drm_panel_bridge_add_typed() with drm_panel_get()
and release it in each teardown path.

tc_aux_transfer() clamps an AUX read to the payload limit:
size_t size = min_t(size_t, DP_AUX_MAX_PAYLOAD_BYTES - 1, msg->size);
After the transfer it replaces size with the byte count the controller
reports in AUX_BYTES:
if (size)
size = FIELD_GET(AUX_BYTES, auxstatus);
AUX_BYTES is GENMASK(15, 8), so it can be up to 255. Nothing clamps it
back to the request. tc_aux_read_data() reads that many bytes into the
16-byte auxrdata stack buffer, then copies them into the caller buffer. A
reported count of 255 makes the read run to 256 bytes and overruns both.
The controller should never report more than it was asked to transfer, so
this is defense in depth rather than a live hole. The reported count is
only lightly trusted, and the check is cheap. Clamp it back to the request,
the same way ti-sn65dsi86 does in commit aca58eac52b8 ("drm/bridge:
ti-sn65dsi86: Never store more than msg->size bytes in AUX xfer").

Replace hardcoded fixed usleep_range() delays during clock recovery and
channel equalization with drm_dp_link_train_clock_recovery_delay()
and drm_dp_link_train_channel_eq_delay() helpers.
The original fixed delays are only valid for the case where bit[6:0] of
DPCD TRAINING_AUX_RD_INTERVAL(0000Eh) is 0x00, while core helpers apply
spec-compliant timings matching actual receiver capability values.
Additionally, add dpcd buffer to struct analogix_dp_device to cache
receiver capabilities. Call drm_dp_read_dpcd_caps() at commit entry to
populate cached DPCD data for subsequent link training steps, and
prepare for further usage of other DP helper APIs.

VS/PE values returned by drm_dp_get_adjust_request_voltage() and
drm_dp_get_adjust_request_pre_emphasis() are already encoded to their
native DPCD register bit positions. However, DPCD_VOLTAGE_SWING_SET /
DPCD_PRE_EMPHASIS_SET macros perform an extra internal shift. Feeding
the raw offset-bearing values directly leads to overlapping bitfields
and invalid lane training configuration, causing link training failures
and black screen.
Add right shift using DP_TRAIN_*_SHIFT constants to strip the DPCD bit
offsets before passing values to the SET macros and subsequent checks.
Apply this fix for both clock recovery and adjust training code paths.
