drm/bridge: analogix_dp: Add new API analogix_dp_finish_probe()
Since the panel/bridge should logically be positioned behind the
Analogix bridge in the display pipeline, it makes sense to handle
the panel/bridge parsing on the Analogix side. Therefore, we add
a new API analogix_dp_finish_probe(), which combines the panel/bridge
parsing with component addition, to do it.
In order to process component binding right after the probe completes,
the &analogix_dp_plat_data.ops is newly added to pass &component_ops,
for which the &dp_aux_ep_device_with_data.done_probing() of DP AUX bus
only supports passing &drm_dp_aux.

drm/bridge: samsung-dsim: samsung_dsim_host_attach: convert to of_drm_find_and_get_bridge()
of_drm_find_bridge() is deprecated. Move to its replacement
of_drm_find_and_get_bridge() which gets a bridge reference, and ensure it
is put when done. Also switch to the drm_bridge::next_bridge pointer.
This needs to handle both cases: when of_drm_find_panel() succeeds and when
it fails.
In the 'else' case (i.e. when of_drm_find_panel() fails), just switch to
of_drm_find_and_get_bridge() to ensure the bridge is not freed while in use
in the function tail, when it is stored in dsi->bridge.next_bridge.
In the 'then' case (i.e. when of_drm_find_panel() succeeds),
devm_drm_panel_bridge_add() already increments the refcount using devres
which ties the bridge allocation lifetime to the device lifetime, so we
would not need to do anything. However to have the same behaviour in both
branches take an additional reference here, so that the bridge needs to be
put whichever branch is taken without more complicated logic. Ensure to
clear the bridge pointer however, to avoid calling drm_bridge_put() on an
ERR_PTR.

drm/bridge: dw-hdmi-qp: Fixup timer base setup
Currently the TIMER_BASE_CONFIG0 register gets initialized to a fixed
value as initially found in vendor driver code supporting the RK3588
SoC. As a matter of fact the value matches the rate of the HDMI TX
reference clock, which is roughly 428.57 MHz.
However, on RK3576 SoC that rate is slightly lower, i.e. 396.00 MHz, and
the incorrect register configuration breaks CEC functionality.
Set the timer base according to the actual reference clock rate that
shall be provided by the platform driver. Otherwise fallback to the
vendor default.
While at it, also drop the unnecessary empty lines in
dw_hdmi_qp_init_hw().

drm/bridge: imx: add driver for HDMI TX Parallel Audio Interface
The HDMI TX Parallel Audio Interface (HTX_PAI) is a digital module that
acts as the bridge between the Audio Subsystem to the HDMI TX Controller.
This IP block is found in the HDMI subsystem of the i.MX8MP SoC.
Data received from the audio subsystem can have an arbitrary component
ordering. The HTX_PAI block has integrated muxing options to select which
sections of the 32-bit input data word will be mapped to each IEC60958
field. The HTX_PAI_FIELD_CTRL register contains mux selects to
individually select P,C,U,V,Data, and Preamble.
Use component helper so that imx8mp-hdmi-tx will be aggregate driver,
imx8mp-hdmi-pai will be component driver, then imx8mp-hdmi-pai can use
bind() ops to get the plat_data from imx8mp-hdmi-tx device.
