Replace the #include of <linux/mod_devicetable.h> by the more specific
<linux/device-id/*.h> where applicable. For most cases the include
can be dropped completely, only a few drivers need one or two headers
added.

Pull gpio updates from Bartosz Golaszewski:
"There's one new driver, one legacy driver removed, a kunit test-suite
for the GPIO core, support for new models in existing drivers and a
slew of various changes in many places though I can't think of
anything controversial that would stand out - it's been a relatively
calm cycle.

fwnode_gpiod_get()
- Quarantine all legacy GPIO APIs in linux/gpio/legacy.h
- Use __ro_after_init where applicable
New drivers:
- Add driver for the GPIO controller on Waveshare DSI TOUCH panels

Allwinner driver changes for 7.2
Mostly changes to the SRAM driver to allow for one SRAM region to be
"claimed" by multiple changes. When a region is "claimed" it is removed
or disconnected from the CPU's view. This is needed on the H6 and H616,
which have one alias region seemingly shared between the video codec
engine and the display engine.
One minor fix for the RSB driver is also included.

Commit b4d01c5b9a9d ("bus: mhi: host: pci_generic: Read SUBSYSTEM_VENDOR_ID
for VF's to check status") added the check for physical function by
checking for 'pdev->is_physfn. But 'pdev->is_physfn' is only set for the
physical function of a SR-IOV capable device. But for the non-SR-IOV device
this variable will be 0. So this check ended up breaking the health check
functionality for all non-SR-IOV devices.
Fix it by checking for '!pdev->is_virtfn' to make sure that the check is
only skipped for virtual functions.

The register address was already validated for read operations in
regmap_sunxi_rsb_reg_read before being truncated to a u8. Write operations
have the same set of possible addresses, and the address is being truncated
from u32 to u8 here as well, so the same check is needed.

The mhi_cntrl->mhi_state field should be protected by state_lock to
ensure atomic state transitions. However, mhi_ep_power_up() access
mhi_state without holding this lock, which can race with concurrent state
transitions and lead to state corruption.
Add proper state_lock protection around mhi_state access.

There is a potential deadlock scenario in mhi_ep_reset_worker() where
the state_lock mutex is acquired twice in the same call chain:
mhi_ep_reset_worker()
mutex_lock(&mhi_cntrl->state_lock)
mhi_ep_power_up()
mhi_ep_set_ready_state()
mutex_lock(&mhi_cntrl->state_lock) <- Deadlock
Fix this by releasing the state_lock before calling mhi_ep_power_up().
The lock is only needed to protect current MHI state read operation. The
lock can be safely released before proceeding with the power up sequence.

When an MHI device uses standard MSI, the PCI core requires the allocated
number of vectors to be a strict power of two. But devices will only ask
for the irqs they need, so they might not be properly aligned.

When a driver is probed through __driver_attach(), the bus' match()
callback is called without the device lock held, thus accessing the
driver_override field without a lock, which can cause a UAF.
Fix this by using the driver-core driver_override infrastructure taking
care of proper locking internally.
Note that calling match() from __driver_attach() without the device lock
held is intentional. [1]

There are use cases in which the Management Complex firmware boot
process is started by the bootloader which does not wait for the boot to
complete. This is mainly done in order to reduce the overall boot time
of a DPAA2 based SoC.
In this kind of circumstance, the fsl-mc bus driver needs to make sure
that the MC firmware boot process is finished before proceeding to the
usual operations such as interrogating the firmware to gather all
existent DPAA2 objects, creating the fsl-mc devices on the bus etc.
Add this kind of check early in the boot process of the fsl-mc bus and
defer the probe in case the firmware is still in its boot process.

In various places in the kernel, we modify the fwnode "flags" member
by doing either:
fwnode->flags |= SOME_FLAG;
fwnode->flags &= ~SOME_FLAG;
This type of modification is not thread-safe. If two threads are both
mucking with the flags at the same time then one can clobber the
other.
While flags are often modified while under the "fwnode_link_lock",
this is not universally true.
Create some accessor functions for setting, clearing, and testing the
FWNODE flags and move all users to these accessor functions. New
accessor functions use set_bit() and clear_bit(), which are
thread-safe.

Some modem devices can take significant time (up to 20 secs for sdx75) to
enter mission mode during initialization. Currently, mhi_sync_power_up()
waits for this entire process to complete, blocking other driver probes
and delaying system boot.
Switch to mhi_async_power_up() so probe can return immediately while MHI
initialization continues in the background. This eliminates lengthy boot
delays and allows other drivers to probe in parallel, improving overall
system boot performance.

QDU100 device
Enable IP_SW1 (ch:48/49), IP_ETH0 (ch:50,51) and IP_ETH1 (ch:52,
53) channels over MHI for M-plane, NETCONF and S-plane interface
for Qualcomm 5G DU X100 Accelerator Card (QDU100).
M-plane:
Used to implement DU M-Plane software for non-real-time O-RAN management
between O-DU and O-RU using NETCONF/YANG and O-RAN WG4 M-Plane YANG models.
It provides capability exchange, configuration management, performance
monitoring, and fault management per O-RAN.WG4.TS.MP.0-R004-v18.00 spec.
Netconf:
Used for configuration operations such as fetching, modifying, and deleting
network device configurations.
This interface is also used for IETF Netconf communication, with a Netconf
server on the ORU to interact with a Netconf client running on the host.
S-plane:
To support frequency and time synchronization between O-DUs and O-RUs using
Synchronous Ethernet and IEEE 1588. Assume PTP transport over L2 Ethernet
(ITU-T G.8275.1) for full timing support and to allow PTP over UDP/IP
(ITU-T G.8275.2) with reduced reliability, as per ORAN spec

The sdma script app_2_mcu needs the permission to access the peripheral
devices:
1) SDMA2 transactions are set to user-mode in this particular case.
2) This type of script doesn't use the peripheral interface (connected
directly to SPBA), but it uses the peripheral DMA interface, then the
SDMA2-issued transactions are subjected to AIPSTZ5's security-related
checks.
So need to clear the Supervisor Protect bit of SPBA2, otherwise the sdma
script can't work. As the imx-aipstz is a common driver for all aips bus,
so set default value (zero) for all opacr registers.

This converts some of the visually simpler cases that have been split
over multiple lines. I only did the ones that are easy to verify the
resulting diff by having just that final GFP_KERNEL argument on the next
line.
Somebody should probably do a proper coccinelle script for this, but for
me the trivial script actually resulted in an assertion failure in the
middle of the script. I probably had made it a bit _too_ trivial.
So after fighting that far a while I decided to just do some of the
syntactically simpler cases with variations of the previous 'sed'
scripts.
The more syntactically complex multi-line cases would mostly really want
whitespace cleanup anyway.
