There is no point to enter safe mode during DP/TBT configuration
if the DP/TBT was already configured in mux. This is because safe
mode is only applicable when there is a need to reconfigure the
pins in order to avoid damage within/to port partner.
In some chrome systems, IOM/mux is already configured before OS
comes up. Thus, when driver is probed, it blindly enters safe
mode due to PD negotiations but only after gfx driver lowers
dp_phy_ownership, will the IOM complete safe mode and send an
ack to PMC.
Since, that never happens, we see IPC timeout.
Hence, allow safe mode only when pin reconfiguration is not
required, which makes sense.

Checking the connection status of every port on resume. This
fixes an issue where the partner device is not unregistered
properly after resume if it was unplugged while the system
was suspended.
The function ucsi_check_connection() is also modified so
that it can be used also for registering the connection on
top of unregistering it.

Here is the big set of USB and Thunderbolt driver changes for 6.1-rc1.
Nothing major in here, lots of little things with new devices supported
and updates for a few drivers. Highlights include:
- thunderbolt/USB4 devices supported a bit better than before,
and some new ids to enable new hardware devices
- USB gadget uvc updates for newer video formats and better v4l
integration (the v4l portions were acked by those maintainers)
- typec updates for tiny issues and more typec drivers for new
chips.
- xhci tiny updates for minor issues
- big usb-serial ftdi_sio driver update to handle new devices
better
- lots of tiny dwc3 fixes and updates for the IP block that is
showing up everywhere these days
- dts updates for new devices being supported
- other tiny janitorial and cleanups fixes for lots of different
USB drivers. Full details are in the shortlog.
All of these have been in linux-next for a while with no reported
issues.

The recent commit 87d0e2f41b ("usb: typec: ucsi: add a common
function ucsi_unregister_connectors()") introduced a regression that
caused NULL dereference at reading the power supply sysfs. It's a
stale sysfs entry that should have been removed but remains with NULL
ops. The commit changed the error handling to skip the entries after
a NULL con->wq, and this leaves the power device unreleased.
For addressing the regression, the straight revert is applied here.
Further code improvements can be done from the scratch again.

Fix incorrect pin assignment values when connecting to a monitor with
Type-C receptacle instead of a plug.
According to specification, an UFP_D receptacle's pin assignment
should came from the UFP_D pin assignments field (bit 23:16), while
an UFP_D plug's assignments are described in the DFP_D pin assignments
(bit 15:8) during Mode Discovery.
For example the LG 27 UL850-W is a monitor with Type-C receptacle.
The monitor responds to MODE DISCOVERY command with following
DisplayPort Capability flag:
dp->alt->vdo=0x140045
The existing logic only take cares of UPF_D plug case,
and would take the bit 15:8 for this 0x140045 case.
This results in an non-existing pin assignment 0x0 in
dp_altmode_configure.
To fix this problem a new set of macros are introduced
to take plug/receptacle differences into consideration.

This adds the necessary ACPI ID for Intel Meteor Lake
IOM devices.
The callback function is_memory() is modified so that it
also checks if the resource descriptor passed to it is a
memory type "Address Space Resource Descriptor".
On Intel Meteor Lake the ACPI memory resource is not
described using the "32-bit Memory Range Descriptor" because
the memory is outside of the 32-bit address space. The
memory resource is described using the "Address Space
Resource Descriptor" instead.
Intel Meteor Lake is the first platform to describe the
memory resource for this device with Address Space Resource
Descriptor, but it most likely will not be the last.
Therefore the change to the is_memory() callback function
is made generic.

The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

STM32G0 comes with STM32 bootloader in its system memory. Add support
for some I2C bootloader commands as described in application notes
AN2606 and AN4221, to enable STM32G0 UCSI firmware update.
Upon probing, the driver needs to know the STM32G0 state:
- In bootloader mode, STM32 G0 answers at i2c addr 0x51.
- In running mode, STM32 G0 firmware may answer at two address.
- The main address specified in DT is used for UCSI.
- 0x51 addr can be re-used for FW controls like getting software version
or jump to booloader request.
So probe using the main firmware i2c address first, before attempting
bootloader address (e.g. check for blank, erased or previously aborted
firmware update).

STM32G0 provides an integrated USB Type-C and power delivery interface.
It can be programmed with a firmware to handle UCSI protocol over I2C
interface. A GPIO is used as an interrupt line.
Type-C connector can be used as a wakeup source (typically to detect
changes on the port, like attach or detach). PM suspend / resume routines
are used to enable wake irqs, and signal a wakeup event in case the IRQ
has fired while in suspend. The i2c core is doing the necessary
initialization when the "wakeup-source" flag is provided.
Note: the interrupt handler shouldn't be called before the i2c bus resumes.
So, the interrupts are disabled during suspend period, and re-enabled
upon resume, to avoid i2c transfer while suspended, from the irq handler.

The fwnode_connection_find_match() function handles two cases: named
references and graph endpoints. In the second case, the match function
passed in is called with the id to check for the match. However, the
match function for the recently added type-c retimer class assumes the
connection has already been matched (which is only true for the first
case).
The result is that with that change, all type-c nodes with graph
endpoints defer probe indefinitely, independently of having a retimer
connection or not.
Add the missing check, like is done by the type-c mux and usb role
switch code, to fix the issue.
