vmlinux fails on the following symbols:
  ld.lld: error: undefined symbol: devm_drm_bridge_add
  ld.lld: error: undefined symbol: devm_drm_of_get_bridge

Add dependendy on DRM || DRM=no since CONFIG_DRM dependency is optional
and guarded by:
IS_ENABLED(CONFIG_OF) && IS_ENABLED(CONFIG_DRM_PANEL_BRIDGE)
in the drive.

Also add "select DRM_PANEL_BRIDGE if DRM" to clarify DRM_PANEL_BRIDGE
is required if CONFIG_DRM is enabled.

power_supply_is_system_supplied() checks whether any power
supplies are present that aren't batteries to decide whether
the system is running on DC or AC.  Downstream drivers use
this to make performance decisions.

Navi dGPUs include an UCSI function that has been exported

This UCSI function registers a power supply since commit

but this is not a system power supply.

As the power supply for a dGPU is only for powering devices connected
to dGPU, create a device property to indicate that the UCSI endpoint
is only for the scope of `POWER_SUPPLY_SCOPE_DEVICE`.

922c0cb578 usb: typec: qcom-pmic-typec: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart from
emitting a warning) and this typically results in resource leaks. To improve
here there is a quest to make the remove callback return void. In the first
step of this quest all drivers are converted to .remove_new() which already
returns void. Eventually after all drivers are converted, .remove_new() is
renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

fc4ecc0cd5 usb: typec: ucsi: acpi: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart from
emitting a warning) and this typically results in resource leaks. To improve
here there is a quest to make the remove callback return void. In the first
step of this quest all drivers are converted to .remove_new() which already
returns void. Eventually after all drivers are converted, .remove_new() is
renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

a4422ff221 usb: typec: qcom: Add Qualcomm PMIC Type-C driver
This commit adds a QCOM PMIC TCPM driver with an initial pm8150b
block.

The driver is layered as follows:

qcom_pmic_typec.c : Responsible for registering with TCPM and arbitrates
                    access to the Type-C and PDPHY hardware blocks in one
                    place.  This presents a single TCPM device to device to
                    the Linux TCPM layer.

qcom_pmic_typec_pdphy.c: Responsible for interfacing with the PDPHY hardware and
                         processing power-delivery related calls from TCPM.
                         This hardware binding can be extended to
                         facilitate similar hardware in different PMICs.

qcom_pmic_typec_port.c: Responsible for notifying and processing Type-C
                        related calls from TCPM. Similar to the pdphy this
                        layer can be extended to handle the specifics of
                        different Qualcomm PMIC Type-C port managers.

This code provides all of the same functionality as the existing
qcom typec driver plus power-delivery as well.

As a result commit 6c8cf3695176 ("usb: typec: Add QCOM PMIC typec detection
driver") can be deleted entirely.

References code from Jonathan Marek, Jack Pham, Wesley Cheng, Hemant Kumar,
Guru Das Srinagesh and Ashay Jaiswal.

556eb8b791 Driver core changes for 6.4-rc1
Here is the large set of driver core changes for 6.4-rc1.
 
 Once again, a busy development cycle, with lots of changes happening in
 the driver core in the quest to be able to move "struct bus" and "struct
 class" into read-only memory, a task now complete with these changes.
 
 This will make the future rust interactions with the driver core more
 "provably correct" as well as providing more obvious lifetime rules for
 all busses and classes in the kernel.
 
 The changes required for this did touch many individual classes and
 busses as many callbacks were changed to take const * parameters
 instead.  All of these changes have been submitted to the various
 subsystem maintainers, giving them plenty of time to review, and most of
 them actually did so.
 
 Other than those changes, included in here are a small set of other
 things:
   - kobject logging improvements
   - cacheinfo improvements and updates
   - obligatory fw_devlink updates and fixes
   - documentation updates
   - device property cleanups and const * changes
   - firwmare loader dependency fixes.
 
 All of these have been in linux-next for a while with no reported
 problems.

eddebe3960 usb: typec: altmodes/displayport: Fix configure initial pin assignment
While determining the initial pin assignment to be sent in the configure
message, using the DP_PIN_ASSIGN_DP_ONLY_MASK mask causes the DFP_U to
send both Pin Assignment C and E when both are supported by the DFP_U and
UFP_U. The spec (Table 5-7 DFP_U Pin Assignment Selection Mandates,
VESA DisplayPort Alt Mode Standard v2.0) indicates that the DFP_U never
selects Pin Assignment E when Pin Assignment C is offered.

Update the DP_PIN_ASSIGN_DP_ONLY_MASK conditional to intially select only
Pin Assignment C if it is available.

326e1c208f usb: typec: ucsi: acpi: add quirk for ASUS Zenbook UM325
On some ACPI platforms (namely the ASUS Zenbook UM325) the _DSM method must
not be called after a notification is received but instead the mailbox
should be read immediately from RAM. This is because the ACPI interrupt
handler destroys the CCI in ERAM after copying to system memory, and when
_DSM is later called to perform a second copy, it retrieves a garbage
value.

Instead, the _DSM(read) method should only be called when necessary, i.e.
for polling the state after reset and for retrieving the version. Other
reads should not call _DSM and only peek into the RAM region.

This adds a separate read operation for the Zenbook that syncs the
ACPI mailbox only with polled commands.

Introduce the UCSI PMIC Glink aux driver that communicates
with the aDSP firmware with the UCSI protocol which handles
the USB-C Port(s) Power Delivery.

The UCSI messaging is necessary on newer Qualcomm SoCs to
provide USB role switch and altmode notifications.

9d11b13402 USB: mark all struct bus_type as const
Now that the driver core can properly handle constant struct bus_type,
move all of the USB subsystem struct bus_type structures as const,
placing them into read-only memory which can not be modified at runtime.

10a03c36b7 drivers: remove struct module * setting from struct class
There is no need to manually set the owner of a struct class, as the
registering function does it automatically, so remove all of the
explicit settings from various drivers that did so as it is unneeded.

This allows us to remove this pointer entirely from this structure going
forward.
