There are only two users of struct pci_platform_pm_ops in the tree,
one of which is Intel MID PM and the other one is ACPI. They are
mutually exclusive and the MID PM should take precedence when they
both are enabled, but whether or not this really is the case hinges
on the specific ordering of arch_initcall() calls made by them.
The struct pci_platform_pm_ops abstraction is not really necessary
for just these two users, but it adds complexity and overhead because
of retoplines involved in using all of the function pointers in there.
It also makes following the code a bit more difficult than it would
be otherwise.
Moreover, Intel MID PCI PM doesn't even implement the majority of the
function pointers in struct pci_platform_pm_ops in a meaningful way,
so switch over the PCI core to calling the relevant MID PM routines,
mid_pci_set_power_state() and mid_pci_set_power_state(), directly as
needed and drop mid_pci_platform_pm.

Notice that it is not necessary to look for the "ACPI bus type" of
the device in acpi_device_notify() if the device's ACPI companion
is set upfront, so modify the code to do that lookup only if it is
necessary to find the ACPI companion.
Also notice that if the device's ACPI companion is not set upfront
in acpi_device_notify(), the device cannot be either a PCI one or a
platform one, so check for these bus types only if the device's
ACPI companion is set.

Since PCI was the only user of the ->cleanup callback in struct
acpi_bus_type and it is not using struct acpi_bus_type any more,
drop that callback from there and update acpi_device_notify_remove()
accordingly.

The acpi_pci_bus structure was used primarily for running
acpi_pci_find_companion() during PCI device objects registration,
but after commit 375553a93201 ("PCI: Setup ACPI fwnode early and at
the same time with OF") that function is called by pci_setup_device()
via pci_set_acpi_fwnode(), which happens before calling
pci_device_add() on the new PCI device object, so its ACPI companion
has been set already when acpi_device_notify() runs and it will never
call ->find_companion() from acpi_pci_bus.
For this reason, modify acpi_device_notify() and
acpi_device_notify_remove() to call pci_acpi_setup() and
pci_acpi_cleanup(), respectively, directly on PCI device objects
and drop acpi_pci_bus altogether.
While at it, notice that pci_acpi_setup() and pci_acpi_cleanup()
can obtain the ACPI companion pointer, which is guaranteed to not
be NULL, from their callers and modify them to work that way so
as to reduce the number of redundant checks somewhat.

Even with the previous commit 27af8e2c90fb
("leds: trigger: fix potential deadlock with libata")
to this file, we still get lockdep unhappy, and Boqun
explained the report here:
https://lore.kernel.org/r/YNA+d1X4UkoQ7g8a@boqun-archlinux
Effectively, this means that the read_lock_irqsave() isn't
enough here because another CPU might be trying to do a
write lock, and thus block the readers.
This is all pretty messy, but it doesn't seem right that
the LEDs framework imposes some locking requirements on
users, in particular we'd have to make the spinlock in the
iwlwifi driver always disable IRQs, even if we don't need
that for any other reason, just to avoid this deadlock.
Since writes to the led_cdevs list are rare (and are done
by userspace), just switch the list to RCU. This costs a
synchronize_rcu() at removal time so we can ensure things
are correct, but that seems like a small price to pay for
getting lock-free iterations and no deadlocks (nor any
locking requirements imposed on users.)

gcc-10 and later warn about a theoretical array overrun when

The warning is a bit strange since it's not actually about the array
bounds but rather about possible string operations with overlapping
arguments, but it's not technically wrong.
Avoid the warning by adding an extra bounds check.

Same members of the Marvell Ethernet switches impose MTU restrictions
on ports used for connecting to the CPU or another switch for DSA. If
the MTU is set too low, tagged frames will be discarded. Ensure the
worst case tagger overhead is included in setting the MTU for DSA and
CPU ports.

The MTU passed to the DSA driver is the payload size, typically 1500.
However, the switch uses the frame size when applying restrictions.
Adjust the MTU with the size of the Ethernet header and the frame
checksum. The VLAN header also needs to be included when the frame
size it per port, but not when it is global.

This patch adds driver for Cadence's XSPI controller.
It supports 3 work modes.
1. ACMD (auto command) work mode
ACMD name is because it uses auto command engine in the controller.
It further has 2 modes PIO and CDMA (command DMA).
The CDMA work mode is dedicated for high-performance application
where very low software overhead is required. In this mode the
Command Engine is programmed by the series of linked descriptors
stored in system memory. These descriptors provide commands to execute
and store status information for finished commands.
The PIO mode work mode is dedicated for single operation where
constructing a linked list of descriptors would require too
much effort.
2. STIG (Software Triggered Instruction Generator) work mode
In STIG mode, controller sends low-level instructions to memory.
Each instruction is 128-bit width. There is special instruction
DataSequence which carries information about data phase.
Driver uses Slave DMA interface to transfer data as only this
interface can be used in STIG work mode.
3. Direct work mode
This work mode allows sending data without invoking any command through
the slave interface.
Currently only STIG work mode is enabled, remaining work modes will
be added later.

debugfs code complained at boot time that
debugfs: Directory 'reg-dummy-regulator-dummy' with parent 'regulator'
already present!
if we compile kernel with DEBUG_TEST_DRIVER_REMOVE. The problem is that we
don't provide .remove() method for dummy_regulator_driver, which should
invoke regulator_unregister() on device teardown to properly free things.
Though it's harmless as dummy_pdev never gets unbound in practice, let's
use devm_regulator_register() to get rid of the inconsistency.
