In case the downstream bridge or panel uses DSI transfers before the
DSI host was actually initialized through samsung_dsim_atomic_enable()
which clears the stop state (LP11) mode, all transfers will fail.

This happens with downstream bridges that are controlled by DSI
commands such as the tc358762.

As documented in [1] DSI hosts are expected to allow transfers
outside the normal bridge enable/disable flow.

To fix this make sure that stop state is cleared in
samsung_dsim_host_transfer() which restores the previous
behavior.

We also factor out the common code to enable/disable stop state
to samsung_dsim_set_stop_state().

<content type='text'>
The ELD (EDID-Like Data) is not updated when the HDMI cable
is plugged into different HDMI monitors.
This is because the EDID is not updated in the HDMI HPD function.
As a result, the ELD data remains unchanged and may not reflect
the capabilities of the newly connected HDMI sink device.

To address this issue, the handle_plugged_change function should move to
the bridge_atomic_enable and bridge_atomic_disable functions.
Make sure the EDID is properly updated before updating ELD.

This reverts commit 8ddce13ae696 ("drm/bridge: lt9611: Do not generate
HFP/HBP/HSA and EOT packet") to fix display regression on the Dragonboard
845c (SDM845) devboard.

There's a mismatch on the real action of the following flags:
- MIPI_DSI_MODE_VIDEO_NO_HSA
- MIPI_DSI_MODE_VIDEO_NO_HFP
- MIPI_DSI_MODE_VIDEO_NO_HBP
which leads to a non-working display on qcom platforms.

<title>drm/bridge: it6505: Check power state with it6505-&gt;powered in IRQ handler</title>

On system resume, the driver might call it6505_poweron directly if the
runtime PM hasn't been enabled. In such case, pm_runtime_get_if_in_use
will always return 0 because dev-&gt;power.runtime_status stays at
RPM_SUSPENDED, and the IRQ will never be handled.

Use it6505-&gt;powered from the driver struct fixes this because it always
gets updated when it6505_poweron is called.

CEC interrupt status/mask and logical address registers
will be reset when device enter suspend.
It will cause cec fail to work after device resume.
Add CEC suspend/resume functions, reinitialize logical address registers
and restore interrupt status/mask registers after resume.

When building with W=1, the following warning occurs.

drivers/gpu/drm/bridge/analogix/analogix-anx78xx.c:48:17: warning: ‘anx781x_i2c_addresses’ defined but not used [-Wunused-const-variable=]  static const u8 anx781x_i2c_addresses[] = {

When CONFIG_IO is disabled, above two variables are not used,
since the place where it is used is inclueded in the macro
CONFIG_OF.

Even for drivers that do not depend on CONFIG_OF, it's almost
always better to leave out the of_match_ptr(), since the only
thing it can possibly do is to save a few bytes of .text if a
driver can be used both with and without it. Hence we remove
all of_match_ptr() used in other places.
