Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>:
In some cs42l43 systems a couple of cs35l56 amplifiers are attached
to the cs42l43's SPI and I2S. On Windows the cs42l43 is controlled
by a SDCA class driver and these two amplifiers are controlled by
firmware running on the cs42l43. However, under Linux the decision
was made to interact with the cs42l43 directly, affording the user
greater control over the audio system. However, this has resulted
in an issue where these two bridged cs35l56 amplifiers are not
populated in ACPI and must be added manually. There is at least an
SDCA extension unit DT entry we can key off.
The process of adding this is handled using a software node, firstly the
ability to add native chip selects to software nodes must be added.
Secondly, an additional flag for naming the SPI devices is added this
allows the machine driver to key to the correct amplifier. Then finally,
the cs42l43 SPI driver adds the two amplifiers directly onto its SPI
bus.
An additional series will follow soon to add the audio machine driver
parts (in the sof-sdw driver), however that is fairly orthogonal to
this part of the process, getting the actual amplifiers registered.

A couple of additional refactorings on top of the multi-CS support.
One is to make sure that the comment and the code are not disrupted
if additional changes come in the future and second one is f or the
sake of deduplication. In both cases it also makes indentation level
smaller in the affected pieces of the code.
No functional changes intended.

Check for the presence of the "01fa-cirrus-sidecar-instances" property
in the SDCA extension unit's ACPI properties to confirm the presence
of these two amplifiers and if they exist add them manually onto the
SPI bus.

Update the name for software node based SPI devices to use the fwnode
name as the device name. This is helpful since swnode devices are
usually added within the kernel, and the kernel often then requires a
predictable name such that it can refer back to the device.

SPI devices can specify a cs-gpios property to enumerate their
chip selects. Under device tree, a zero entry in this property can
be used to specify that a particular chip select is using the SPI
controllers native chip select, for example:
cs-gpios = <&gpio1 0 0>, <0>;
Here, the second chip select is native. However, when using swnodes
there is currently no way to specify a native chip select. The
proposal here is to register a swnode_gpio_undefined software node,
that can be specified to allow the indication of a native chip
select. For example:
static const struct software_node_ref_args device_cs_refs[] = {
{
.node = &device_gpiochip_swnode,
.nargs = 2,
.args = { 0, GPIO_ACTIVE_LOW },
},
{
.node = &swnode_gpio_undefined,
.nargs = 0,
},
};
Register the swnode as the gpiolib is initialised and check in
swnode_get_gpio_device() if the returned node matches
swnode_gpio_undefined and return -ENOENT, which matches the
behaviour of the device tree system when it encounters a 0 phandle.

Refactor code for "is the node's child available?" check by using the
corresponding macro instead, which reads more clearly.
While at it, use scope-based cleanup instead of manual of_node_put()
calls when getting platform data through cdns_xspi_of_get_plat_data().
This removes the unnecessary "node_child" declaration out of the loop's
scope and auto cleans up "node_child" when it goes out of scope, even
when we return early due to error.

cqspi_enable_dtr() is called for each operation, commands or not, reads
or writes. It writes CQSPI_REG_CONFIG then waits for idle (three
successful reads). Skip that in the no-DTR case if DTR is already
disabled.
It cannot be skipped in the DTR case as cqspi_setup_opcode_ext() writes
to a register and we must wait for idle state.
According to ftrace, the average cqspi_exec_mem_op() call goes from
85.4µs to 83.6µs when reading 235M over UBIFS on an octal flash.

Avoid of_device_get_match_data() call on each IRQ and each read
operation. Store pointer in `struct cqspi_st` device instance.
End-to-end performance measurements improve with this patch. On a given
octal flash, reading 235M over UBIFS is ~3.4% faster. During that read,
the average cqspi_exec_mem_op() call goes from 85.4µs to 80.7µs
according to ftrace. The worst case goes from 622.4µs to 615.2µs.

firewire: ohci: mask bus reset interrupts between ISR and bottom half
|
|
In the FireWire OHCI interrupt handler, if a bus reset interrupt has
occurred, mask bus reset interrupts until bus_reset_work has serviced and
cleared the interrupt.
Normally, we always leave bus reset interrupts masked. We infer the bus
reset from the self-ID interrupt that happens shortly thereafter. A
scenario where we unmask bus reset interrupts was introduced in 2008 in
a007bb857e0b26f5d8b73c2ff90782d9c0972620: If
OHCI_PARAM_DEBUG_BUSRESETS (8) is set in the debug parameter bitmask, we
will unmask bus reset interrupts so we can log them.
irq_handler logs the bus reset interrupt. However, we can't clear the bus
reset event flag in irq_handler, because we won't service the event until
later. irq_handler exits with the event flag still set. If the
corresponding interrupt is still unmasked, the first bus reset will
usually freeze the system due to irq_handler being called again each
time it exits. This freeze can be reproduced by loading firewire_ohci
with "modprobe firewire_ohci debug=-1" (to enable all debugging output).
Apparently there are also some cases where bus_reset_work will get called
soon enough to clear the event, and operation will continue normally.
This freeze was first reported a few months after a007bb85 was committed,
but until now it was never fixed. The debug level could safely be set
to -1 through sysfs after the module was loaded, but this would be
ineffectual in logging bus reset interrupts since they were only
unmasked during initialization.
irq_handler will now leave the event flag set but mask bus reset
interrupts, so irq_handler won't be called again and there will be no
freeze. If OHCI_PARAM_DEBUG_BUSRESETS is enabled, bus_reset_work will
unmask the interrupt after servicing the event, so future interrupts
will be caught as desired.
As a side effect to this change, OHCI_PARAM_DEBUG_BUSRESETS can now be
enabled through sysfs in addition to during initial module loading.
However, when enabled through sysfs, logging of bus reset interrupts will
be effective only starting with the second bus reset, after
bus_reset_work has executed.

Pull SCSI fixes from James Bottomley:
"The most important is the libsas fix, which is a problem for DMA to a
kmalloc'd structure too small causing cache line interference. The
other fixes (all in drivers) are mostly for allocation length fixes,
error leg unwinding, suspend races and a missing retry"

scsi: ufs: core: Fix MCQ mode dev command timeout

There are a couple of fixups for this cycle's vmalloc changes and one
for the stackdepot changes. And a fix for a very old x86 PAT issue

Pull arm64 fix from Catalin Marinas:
"arm64/ptrace fix to use the correct SVE layout based on the saved
floating point state rather than the TIF_SVE flag. The latter may be
left on during syscalls even if the SVE state is discarded"

Pull RISC-V fixes from Palmer Dabbelt:
- A fix for an __{get,put}_kernel_nofault to avoid an uninitialized
value causing spurious failures
- compat_vdso.so.dbg is now installed to the standard install location
- A fix to avoid initializing PERF_SAMPLE_BRANCH_*-related events, as
they aren't supported and will just later fail
- A fix to make AT_VECTOR_SIZE_ARCH correct now that we're providing
AT_MINSIGSTKSZ
- pgprot_nx() is now implemented, which fixes vmap W^X protection
- A fix for the vector save/restore code, which at least manifests as
corrupted vector state when a signal is taken
- A fix for a race condition in instruction patching
- A fix to avoid leaking the kernel-mode GP to userspace, which is a
kernel pointer leak that can be used to defeat KASLR in various ways
- A handful of smaller fixes to build warnings, an overzealous printk,
and some missing tracing annotations

Pull thermal control fixes from Rafael Wysocki:
"These fix two power allocator thermal governor issues and an ACPI
thermal driver regression that all were introduced during the 6.8
development cycle.
Specifics:
- Allow the power allocator thermal governor to bind to a thermal
zone without cooling devices and/or without trip points (Nikita
Travkin)
- Make the ACPI thermal driver register a tripless thermal zone when
it cannot find any usable trip points instead of returning an error
from acpi_thermal_add() (Stephen Horvath)"
