commit 5090ac9191 upstream.
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

[ Upstream commit a5caf03188 ]
The syscon helper device_node_to_regmap() is used to fetch a regmap
registered to a device node. It also currently creates this regmap
if the node did not already have a regmap associated with it. This
should only be used on "syscon" nodes. This driver is not such a
device and instead uses device_node_to_regmap() on its own node as
a hacky way to create a regmap for itself.
This will not work going forward and so we should create our regmap
the normal way by defining our regmap_config, fetching our memory
resource, then using the normal regmap_init_mmio() function.

commit 2eeb03ad9f upstream.
When some client process A call pdr_add_lookup() to add the look up for
the service and does schedule locator work, later a process B got a new
server packet indicating locator is up and call pdr_locator_new_server()
which eventually sets pdr->locator_init_complete to true which process A
sees and takes list lock and queries domain list but it will timeout due
to deadlock as the response will queued to the same qmi->wq and it is
ordered workqueue and process B is not able to complete new server
request work due to deadlock on list lock.
Fix it by removing the unnecessary list iteration as the list iteration
is already being done inside locator work, so avoid it here and just
call schedule_work() here.
Process A Process B
process_scheduled_works()
pdr_add_lookup() qmi_data_ready_work()

commit 22cf4fae66 upstream.
On MSM8916 devices, the serial number exposed in sysfs is constant and does
not change across individual devices. It's always:
db410c:/sys/devices/soc0$ cat serial_number
2644893864
The firmware used on MSM8916 exposes SOCINFO_VERSION(0, 8), which does not
have support for the serial_num field in the socinfo struct. There is an
existing check to avoid exposing the serial number in that case, but it's
not correct: When checking the item_size returned by SMEM, we need to make
sure the *end* of the serial_num is within bounds, instead of comparing
with the *start* offset. The serial_number currently exposed on MSM8916
devices is just an out of bounds read of whatever comes after the socinfo
struct in SMEM.
Fix this by changing offsetof() to offsetofend(), so that the size of the
field is also taken into account.

Qualcomm driver fixes for v6.12
The Qualcomm EDAC driver's configuration of interrupts is made optional,
to avoid violating security constriants on X Elite platform .
The SCM drivers' detection mechanism for the presence of SHM bridge in QTEE,
is corrected to handle the case where firmware successfully returns that
the interface isn't supported.
The GLINK driver and the PMIC GLINK interface is updated to handle
buffer allocation issues during initialization of the communication
channel.
Allocation error handling in the socinfo dirver is corrected, and then
the fix is corrected.

Some versions of the pmic_glink firmware does not allow dynamic GLINK
intent allocations, attempting to send a message before the firmware has
allocated its receive buffers and announced these intent allocations
will fail. When this happens something like this showns up in the log:
pmic_glink_altmode.pmic_glink_altmode pmic_glink.altmode.0: failed to send altmode request: 0x10 (-125)
pmic_glink_altmode.pmic_glink_altmode pmic_glink.altmode.0: failed to request altmode notifications: -125
ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: failed to send UCSI read request: -125
qcom_battmgr.pmic_glink_power_supply pmic_glink.power-supply.0: failed to request power notifications
GLINK has been updated to distinguish between the cases where the remote
is going down (-ECANCELED) and the intent allocation being rejected
(-EAGAIN).
Retry the send until intent buffers becomes available, or an actual
error occur.
To avoid infinitely waiting for the firmware in the event that this
misbehaves and no intents arrive, an arbitrary 5 second timeout is
used.
This patch was developed with input from Chris Lew.

In success case, the revision holds a non-null pointer. The current
logic incorrectly returns an error for a non-null pointer, whereas
it should return an error for a null pointer.
The socinfo driver for IPQ9574 and IPQ5332 is currently broken,
resulting in the following error message
qcom-socinfo qcom-socinfo: probe with driver qcom-socinfo failed with
error -12
Add a null check for the revision to ensure it returns an error only in
failure case (null pointer).

On most modern qualcomm SoCs, the configuration necessary to enable the
Tag/Data RAM related irqs being propagated to the SoC irq controller is
already done in firmware (in DSF or 'DDR System Firmware')
On some like the x1e80100, these registers aren't even accesible to the
kernel causing a crash when edac device is probed.
Hence, make the irq configuration optional in the driver and mark x1e80100
as the SoC on which this should be avoided.

The driver updates seem larger this time around, with changes
is many of the SoC specific drivers, both the custom drivers/soc
ones and the closely related subsystems (memory, bus, firmware,
reset, ...).
The at91 platform gains support for sam9x7 chips in the soc and
power management code. This is the latest variant of one of the
oldest still supported SoC families, using the ARM9 (ARMv5) core.
As usual, the qualcomm snapdragon platform gets a ton of updates in many
of their drivers to add more features and additional SoC support. Most
of these are somewhat firmware related as the platform has a number of
firmware based interfaces to the kernel. A notable addition here is the
inclusion of trace events to two of these drivers.
Herve Codina and Christophe Leroy are now sending updates for
drivers/soc/fsl/ code through the SoC tree, this contains both PowerPC
and Arm specific platforms and has previously been problematic to
maintain. The first update here contains support for newer PowerPC
variants and some cleanups.
The turris mox firmware driver has a number of updates, mostly cleanups.
The Arm SCMI firmware driver gets a major rework to modularize
the existing code into separately loadable drivers for the various
transports, the addition of custom NXP i.MX9 interfaces and a
number of smaller updates.
The Arm FF-A firmware driver gets a feature update to support
the v1.2 version of the specification.
The reset controller drivers have some smaller cleanups and a newly
added driver for the Intel/Mobileye EyeQ5/EyeQ6 MIPS SoCs.
The memory controller drivers get some cleanups and refactoring
for Tegra, TI, Freescale/NXP and a couple more platforms.
Finally there are lots of minor updates to firmware (raspberry pi,
tegra, imx), bus (sunxi, omap, tegra) and soc (rockchips, tegra, amlogic,
mediatek) drivers and their DT bindings.

Lenovo Thinkpad T14s, providing EFI variable access.
The change to match the SMD RPM driver based on the SMD channel name is
reverted, in favor of stepping back to OF-based matching, as a means to
get module autoloading to work properly.

When TSA is compiled as module the following error is reported:
"ucc_mux_set_grant_tsa_bkpt" [drivers/soc/fsl/qe/tsa.ko] undefined!
Indeed, the ucc_mux_set_grant_tsa_bkpt symbol is not exported.
Simply export ucc_mux_set_grant_tsa_bkpt.
