The typo when using the MODULE_DEVICE_TABLE macro was not noticeable
because the macro was defined only if the module was built as a separate
module.

Typically HDMI to MIPI CSI-2 bridges have a pin to signal image data is
being received. On the host side this is wired to a GPIO for polling or
interrupts. This includes the Lontium HDMI to MIPI CSI-2 bridges
lt6911uxe and lt6911uxc.
The GPIO "hpd" is used already by other HDMI to CSI-2 bridges, use it
here as well.

If an error occurs after a successful iommu_paging_domain_alloc() call, it
should be undone by a corresponding iommu_domain_free() call, as already
done in the remove function.
In order to fix the issue, move the corresponding call at the end of the
function, because it is safe to allocate 'empty_domain' later.

Genpd OF providers must now be registered after genpd bus registration.
However, cpg_mstp_add_clk_domain() is only called from CLK_OF_DECLARE(),
which is too early. Hence on R-Car M1A, R-Car H1, and RZ/A1, the
CPG/MSTP Clock Domain fails to register, and any devices residing in
that clock domain fail to probe.
Fix this by splitting initialization into two steps:
- The first part keeps on registering the PM domain with genpd at
CLK_OF_DECLARE(),
- The second and new part moves the registration of the genpd OF
provider to a postcore_initcall().
See also commit c5ae5a0c61120d0c ("pmdomain: renesas: rcar-sysc: Add
genpd OF provider at postcore_initcall").

The BIOS can leave the AUX power well enabled on an output, even if this
isn't required (on platforms where the AUX power is only needed for an
AUX access). This was observed at least on PTL. To avoid the WARN which
would be triggered by this during the HW readout, convert the WARN to a
debug message.

Use the cached max lane count value on LNL+, to account for scenarios
where this value is queried after the HW cleared the corresponding pin
assignment value in the TCSS_DDI_STATUS register after the sink got
disconnected.
For consistency, follow-up changes will use the cached max lane count
value on other platforms as well and will also cache the pin assignment
value in a similar way.

On LNL+ for a disconnected sink the pin assignment value gets cleared by
the HW/FW as soon as the sink gets disconnected, even if the PHY
ownership got acquired already by the BIOS/driver (and hence the PHY
itself is still connected and used by the display). During HW readout
this can result in detecting the PHY's max lane count as 0 - matching
the above cleared aka NONE pin assignment HW state. For a connected PHY
the driver in general (outside of intel_tc.c) expects the max lane count
value to be valid for the video mode enabled on the corresponding output
(1, 2 or 4). Ensure this by setting the max lane count to 4 in this
case. Note, that it doesn't matter if this lane count happened to be
more than the max lane count with which the PHY got connected and
enabled, since the only thing the driver can do with such an output -
where the DP-alt sink is disconnected - is to disable the output.
v2: Rebased on change reading out the pin configuration only if the PHY
is connected.

The PHY's pin assignment value in the TCSS_DDI_STATUS register - as set
by the HW/FW based on the connected DP-alt sink's TypeC/PD pin
assignment negotiation - gets cleared by the HW/FW on LNL+ as soon as
the sink gets disconnected, even if the PHY ownership got acquired
already by the driver (and hence the PHY itself is still connected and
used by the display). This is similar to how the PHY Ready flag gets
cleared on LNL+ in the same register.
To be able to query the max lane count value on LNL+ - which is based on
the above pin assignment - at all times even after the sink gets
disconnected, the max lane count must be determined and cached during
the PHY's HW readout and connect sequences. Do that here, leaving the
actual use of the cached value to a follow-up change.
v2: Don't read out the pin configuration if the PHY is disconnected.

The TypeC PHY HW readout during driver loading and system resume
determines which TypeC mode the PHY is in (legacy/DP-alt/TBT-alt) and
whether the PHY is connected, based on the PHY's Owned and Ready flags.
For the PHY to be in DP-alt or legacy mode and for the PHY to be in the
connected state in these modes, both the Owned (set by the BIOS/driver)
and the Ready (set by the HW) flags should be set.
On ICL-MTL the HW kept the PHY's Ready flag set after the driver
connected the PHY by acquiring the PHY ownership (by setting the Owned
flag), until the driver disconnected the PHY by releasing the PHY
ownership (by clearing the Owned flag). On LNL+ this has changed, in
that the HW clears the Ready flag as soon as the sink gets disconnected,
even if the PHY ownership was acquired already and hence the PHY is
being used by the display.
When inheriting the HW state from BIOS for a PHY connected in DP-alt
mode on which the sink got disconnected - i.e. in a case where the sink
was connected while BIOS/GOP was running and so the sink got enabled
connecting the PHY, but the user disconnected the sink by the time the
driver loaded - the PHY Owned but not Ready state must be accounted for
on LNL+ according to the above. Do that by assuming on LNL+ that the PHY
is connected in DP-alt mode whenever the PHY Owned flag is set,
regardless of the PHY Ready flag.
This fixes a problem on LNL+, where the PHY TypeC mode / connected state
was detected incorrectly for a DP-alt sink, which got connected and then
disconnected by the user in the above way.
v2: Rename tc_phy_in_legacy_or_dp_alt_mode() to tc_phy_owned_by_display().

Presently in `max_contaminant_is_contaminant()` if there's no
contaminant detected previously, CC is open & stopped toggling and no
contaminant is currently present, TCPC.RC would be programmed to do DRP
toggling. However, it didn't actively look for a connection. This would
lead to Type-C not detect *any* new connections. Hence, in the above
situation, re-enable toggling & program TCPC to look for a new
connection.
Also, return early if TCPC was looking for connection as this indicates
TCPC has neither detected a potential connection nor a change in
contaminant state.
In addition, once dry detection is complete (port is dry), restart
toggling.

comparator values
Low power mode is enabled when reading CC resistance as part of
`max_contaminant_read_resistance_kohm()` and left in that state.
However, it's supposed to work with 1uA current source. To read CC
comparator values current source is changed to 80uA. This causes a storm
of CC interrupts as it (falsely) detects a potential contaminant. To
prevent this, disable low power mode current sourcing before reading
comparator values.

This commit addresses a rarely observed endpoint command timeout
which causes kernel panic due to warn when 'panic_on_warn' is enabled
and unnecessary call trace prints when 'panic_on_warn' is disabled.
It is seen during fast software-controlled connect/disconnect testcases.
The following is one such endpoint command timeout that we observed:
1. Connect
=======
->dwc3_thread_interrupt
->dwc3_ep0_interrupt
->configfs_composite_setup
->composite_setup
->usb_ep_queue
->dwc3_gadget_ep0_queue
->__dwc3_gadget_ep0_queue
->__dwc3_ep0_do_control_data
->dwc3_send_gadget_ep_cmd
2. Disconnect
==========
->dwc3_thread_interrupt
->dwc3_gadget_disconnect_interrupt
->dwc3_ep0_reset_state
->dwc3_ep0_end_control_data
->dwc3_send_gadget_ep_cmd
In the issue scenario, in Exynos platforms, we observed that control
transfers for the previous connect have not yet been completed and end
transfer command sent as a part of the disconnect sequence and
processing of USB_ENDPOINT_HALT feature request from the host timeout.
This maybe an expected scenario since the controller is processing EP
commands sent as a part of the previous connect. It maybe better to
remove WARN_ON in all places where device endpoint commands are sent to
avoid unnecessary kernel panic due to warn.

one is driver CD mode which has Windows driver onboard, another one is
Wi-Fi mode. Add the US_FL_IGNORE_DEVICE quirk for these multi-mode devices.
Otherwise, usb_modeswitch may fail to switch them to Wi-Fi mode.
Currently there are only two USB IDs known to be used by these multi-mode

When stress-testing the system by repeatedly unbinding and binding the ADC
device in a loop, and the ADC is a supplier for another device (e.g., a
thermal hardware block that reads temperature through the ADC), it may
happen that the ADC device is runtime-resumed immediately after runtime PM
is enabled, triggered by its consumer. At this point, since drvdata is not
yet set and the driver's runtime PM callbacks rely on it, a crash can
occur. To avoid this, set drvdata just after it was allocated.

There is no need to manually track the runtime PM status in the driver.
The pm_runtime_force_suspend() and pm_runtime_force_resume() functions
already call pm_runtime_status_suspended() to check the runtime PM state.
Additionally, avoid calling pm_runtime_put_autosuspend() during the
suspend/resume path, as this would decrease the usage counter of a
potential user that had the ADC open before the suspend/resume cycle.

In the do_validate_mem(), the call to add_interval() does not
handle errors. If kmalloc() fails in add_interval(), it could
result in a null pointer being inserted into the linked list,
leading to illegal memory access when sub_interval() is called
next.
This patch adds an error handling for the add_interval(). If
add_interval() returns an error, the function will return early
with the error code.

causes errors:

During raid resync, if a disk becomes faulty, the operation is
briefly interrupted. The MD_RECOVERY_RECOVER flag triggered by
the disk failure causes sync_action to incorrectly show "recover"
instead of "resync". The same issue affects reshape operations.
Reproduction steps:
mdadm -Cv /dev/md1 -l1 -n4 -e1.2 /dev/sd{a..d} // -> resync happened
mdadm -f /dev/md1 /dev/sda // -> resync interrupted
cat sync_action
-> recover
Add progress checks in md_sync_action() for resync/recover/reshape
to ensure the interface correctly reports the actual operation type.

Using device_find_child() and of_find_device_by_node() to locate
devices could cause an imbalance in the device's reference count.
device_find_child() and of_find_device_by_node() both call
get_device() to increment the reference count of the found device
before returning the pointer. In mtk_drm_get_all_drm_priv(), these
references are never released through put_device(), resulting in
permanent reference count increments. Additionally, the
for_each_child_of_node() iterator fails to release node references in
all code paths. This leaks device node references when loop
termination occurs before reaching MAX_CRTC. These reference count
leaks may prevent device/node resources from being properly released
during driver unbind operations.
As comment of device_find_child() says, 'NOTE: you will need to drop
the reference with put_device() after use'.

The reason is that `Getparam::set_value` takes a `u64` (from the UAPI),
but `pci::Device::resource_len()` returns a `resource_size_t`, which is a
`phys_addr_t`, which may be 32- or 64-bit.
Thus add an `into()` call to support the 32-bit case, while allowing the
Clippy lint that complains in the 64-bit case where the type is the same.
