The PMIC GLINK driver is currently generating DisplayPort hotplug
notifications whenever something is connected to (or disconnected from)
a port regardless of the type of notification sent by the firmware.
These notifications are forwarded to user space by the DRM subsystem as
connector "change" uevents:
KERNEL[1556.223776] change /devices/platform/soc@0/ae00000.display-subsystem/ae01000.display-controller/drm/card0 (drm)
ACTION=change
DEVPATH=/devices/platform/soc@0/ae00000.display-subsystem/ae01000.display-controller/drm/card0
SUBSYSTEM=drm
HOTPLUG=1
CONNECTOR=36
DEVNAME=/dev/dri/card0
DEVTYPE=drm_minor
SEQNUM=4176
MAJOR=226
MINOR=0
On the Lenovo ThinkPad X13s and T14s, the PMIC GLINK firmware sends two
identical notifications with orientation information when connecting a
charger, each generating a bogus DRM hotplug event. On the X13s, two
such notification are also sent every 90 seconds while a charger remains
connected, which again are forwarded to user space:
port = 1, svid = ff00, mode = 255, hpd_state = 0
payload = 01 00 00 00 00 00 00 ff 00 00 00 00 00 00 00 00
Note that the firmware only sends on of these when connecting an
ethernet adapter.
Fix the spurious hotplug events by only forwarding hotplug notifications
for the Type-C DisplayPort service id. This also reduces the number of
uevents from four to two when an actual DisplayPort altmode device is
connected:
port = 0, svid = ff01, mode = 2, hpd_state = 0
payload = 00 01 02 00 f2 0c 01 ff 03 00 00 00 00 00 00 00
port = 0, svid = ff01, mode = 2, hpd_state = 1
payload = 00 01 02 00 f2 0c 01 ff 43 00 00 00 00 00 00 00

Arm SCMI updates for v6.16
1. Quirk framework to handle buggy firmware
With SCMI gaining broader adoption across arm64 platforms, it's
increasingly important to address how we consistently manage out-of-spec
SCMI firmware already deployed in the field. This change introduces a
lightweight quirk framework built around static_keys, enabling developers to:
- Define quirks and their match criteria, which can include:
o A list of compatibles ({ comp, comp2, NULL })
o Vendor ID / Sub-Vendor ID
o Firmware implementation version ranges ([Min_Vers, Max_Vers])
Matching proceeds from the most specific (longest match) to the least
specific. NULL entries are treated as wildcards (i.e., match any value).
This flexibility allows matching very specific combinations or just a
general compatible string.
The quirk code blocks/snippets implementing the workaround are placed near
their intended usage and guarded by a static_key that's tied to the quirk.
Once the SCMI core stack is initialized and retrieves platform info via the
base protocol, any matching quirks will have their associated static_keys
enabled.
2. Quirk for Qualcomm X1E platforms
On some Qualcomm X1E platforms, such as the Lenovo ThinkPad T14s, the
SCMI firmware fails to set the FastChannel support bit for PERF_LEVEL_GET,
yet it crashes when the driver attempts to fall back to standard messaging
which is clearly out-of-spec behavior.
To work around this, the new SCMI quirk framework is used to
unconditionally enable FC initialization for this firmware version.
In the future, once the fixed firmware version is identified, an upper
version bound can be added to the quirk match criteria. Alternatively,
matching can be further restricted using a SoC-specific compatible string
if always enabling FC proves problematic elsewhere.
3. Support for NXP i.MX LMM/CPU vendor protocol extensions
The i.MX95 System Manager (SM) implements Logical Machine Management (LMM)
and a CPU protocol to manage Logical Machines (LM) and CPUs (e.g., M7).
These changes integrate the vendor-specific protocol extensions
implementing the LMM and CPU protocols for the i.MX95, facilitating
standardized communication between the operating system and the platform's
firmware, which will be used by remoteproc drivers. The changes also
include the necessary device tree bindings.
4. Miscellaneous cleanups/changes
These mainly include polling support in SCMI raw mode. The cleanups
centralize error logging for SCMI device creation into a single helper
function, consolidate the device matching logic into a single function, and
ensure that devices must have a name for registration—removing support for
unnamed devices when matching drivers and devices for probing. Transport
devices are now excluded from bus matching, and the correct assignment of
the parent device for the arm-scmi platform device is ensured in the
transport drivers.

Commit ad3dd9592b2a ("soc: qcom: pmic_glink: disable UCSI on sc8280xp")
disabled UCSI shortly after it had been enabled to fix a regression that
was observed on the Lenovo ThinkPad X13s.
Specifically, disconnecting an external display would trigger a system
error and hypervisor reset but no one cared enough to track down the bug
at the time.
The same issue was recently observed on X Elite machines, and commit
f47eba045e6c ("usb: typec: ucsi: Set orientation as none when connector
is unplugged") worked around the underlying issue by setting the
connector orientation to 'none' on disconnect events to avoid having the
PHY driver crash the machine in one orientation.
Enable UCSI support also on sc8280xp now that the DisplayPort disconnect
crashes are gone.

Add driver for Sophgo CV1800 series SoC RTC subsystem. The RTC module
comprises a 32kHz oscillator, Power-on-Reset (PoR) sub-module, HW state
machine to control chip power-on, power-off and reset. Furthermore, the
8051 subsystem is located within RTCSYS including associated SRAM block.
This patch only populates RTC sub-device.

Fix CPU resume latency constraint units sent to device manager through the
TI SCI API. The device manager expects CPU resume latency to be in msecs
which is passed in with the TI SCI API [1]. CPU latency constraints are
set in userspace using the PM QoS framework which uses usecs as the unit.
Since PM QoS uses usecs for units and the device manager expects msecs as
the unit, TI SCI needs to convert from usecs to msecs before passing to
device manager.

The Qualcomm SCP firmware in X1E machines like the Lenovo ThinkPad T14s
does not set the FastChannel supported attribute bit for PERF_LEVEL_GET
but crashes when falling back to regular messaging.
Use the new SCMI quirk framework to force FastChannel initialisation for
this implementation.
Note that we can add an upper bound on the version matching when we
learn which version has a fix (or limit matching using a SoC compatible
string in the unlikely event that always enabling FC causes trouble
somewhere).

Triggered by noticing that the pwm-rcar driver isn't covered by the
Renesas maintainer entry, add this driver to it. Instead of adding it
explicitly, just add a file regex for "rcar" (and drop the one entry
that gets redundant by that).
Looking at the output of
$ git ls-files | grep rcar
only shows files related to that architecture, so no X: line is
currently needed.

Add a small SOC bus driver to parse the chip ID and revision made
available on VIA/WonderMedia SoCs via their system configuration
controller's SCC_ID register.
This is intended to select appropriate sets of on-chip device quirks
at runtime, as it has been found that even within the same SoC
version there can be register-incompatible differences, such as
with the SDMMC controller on WM8505 rev. A0-A1 vs. rev. A2.
The list of SoC versions is compiled from various vendor source dumps
and not all of them have corresponding mainline driver support.
Some of them also have been seen with varying on-chip markings while
sharing the same hardware chip ID's (as is the case with e.g. WM8850
vs. WM8950). In such cases the selection of names to use here among
those seen in various source dumps and chip markings was arbitrary.
Suggested by Krzysztof at [1] - thanks a lot!
