The clk_init_data structure contains several mutually-exclusive members
for different methods to specify the possible parents of a clock,
prompting drivers to initialize only the members they need. However,
not initializing all members may cause subtle issues, which are only
exposed when CONFIG_INIT_STACK_ALL_PATTERN or CONFIG_INIT_STACK_NONE is
enabled.
aml_spisg_clk_init() fills in init.parent_data, and assumes that
init.parent_names is NULL. However, the latter in uninitialized, and
thus may cause a crash.
Make sure all members are fully initialized, to fix such bugs, and to
avoid future breakage when converting drivers to a different method for
specifying the parents.

Pull spi updates from Mark Brown:
"Along with a lot of driver specific work we've got a couple of core
features here. The bigger one is that we've now got support for

for I2C, this is used with development boards with non-enumerable
expansion headers since SPI devices need to be manually specified. We
also have support for the DQS signal on higher end flash devices.
- Support for instantiating devices from sysfs, useful for

Honghui Jiang <jiang_hh2019@163.com> says:
A partial DMA mapping failure can leave per-transfer mapping flags set
while cur_{tx,rx}_dma_dev are NULL or still refer to the devices used
for an earlier message. The subsequent cleanup may then unmap a
transfer with a NULL or stale device.
Before commit e289df82344f ("spi: Rework per message DMA mapped flag to
be per transfer"), partial-failure handling was already incomplete, but
__spi_unmap_msg() was gated by cur_msg_mapped, which was set only after
the whole message mapped successfully. Earlier mappings could leak, but
cleanup could not unmap them with an unpublished device. The
per-transfer conversion removed that gate: mapping flags can now remain
set while cur_{tx,rx}_dma_dev are still unpublished, turning the leak
into a NULL- or stale-device unmap regression.
Patch 1 publishes the mapping devices before the loop and unwinds every
failure through __spi_unmap_msg(). It keeps the forward declaration so
it is independently buildable and straightforward to backport. Patch 2
then removes the declaration by moving __spi_unmap_msg() above
__spi_map_msg(). Patch 3 clears the current DMA device pointers once the
message has been unmapped, while leaving them intact during partial-map
unwind and DMA-to-PIO fallback. Patch 4 adds the DMA mapping KUnit suite
as a separate translation unit.
Only patch 1 is a stable candidate; patches 2 through 4 are follow-up
cleanup and test changes for mainline.
Testing:
- Patch 1 builds independently with the x86_64 reproducer configuration.
- The spi_dma KUnit suite passes all four cases on x86_64 and UML.
Moving the DMA device assignments back after the mapping loop makes
both failure-path cases fail.
- The default and all-tests KUnit configurations both select the suite.
- All four reproducer cases complete without an oops when run as the
first message, and map/unmap counts are balanced after a successful
first message.
- After message cleanup, cur_{tx,rx}_dma_dev are NULL.

Add KUnit tests for the __spi_map_msg() error paths. The tests verify
that a later TX or RX mapping failure clears the mapping state of
earlier transfers and leaves cur_{tx,rx}_dma_dev identifying the
current mapping device.
A zero-length transfer causes sg_alloc_table() to return -EINVAL,
providing deterministic failure injection without test hooks.
Additional cases cover successful map/unmap and a message which
requires no mapping.
Build the DMA suite as a separate translation unit, exposing the two
internal mapping helpers only for KUnit through the local internal
header. Enable SPI in the default and all-tests KUnit configurations so
the suite is exercised there.

The current DMA device pointers remain set after a message has been
unmapped. Existing users either check the corresponding mapped flag or
access the pointers before finalizing the message, but retaining stale
device pointers is fragile.
Clear both pointers in spi_unmap_msg() after the internal unmap
completes. Keep them intact in __spi_unmap_msg(), since that helper is
also used during partial-map unwind and the in-message DMA-to-PIO
fallback, before processing of the current message is complete.

If RX mapping fails after TX mapping succeeds, __spi_map_msg() unmaps
TX but leaves tx_sg_mapped set. If TX mapping fails on a later
transfer, mappings created for earlier transfers remain active.
In both cases, cur_{tx,rx}_dma_dev have not yet been updated because they
are assigned only after every transfer has been mapped. The subsequent
spi_unmap_msg() may therefore unmap the TX mapping again or release
earlier mappings using a NULL or stale device. Using a NULL device can
trigger an oops. An empty SG table does not prevent the NULL dereference
because dma_unmap_sg_attrs() accesses the device before checking the
entry count.
Publish both mapping devices before mapping starts and unwind all
failures through __spi_unmap_msg(). This clears the mapping flags and
releases each mapping once with the device that created it.
Publishing the devices before the loop also refreshes them when no
transfer needs mapping. No mapping flag is set in that case, so current
users do not use the pointers as mapping owners.

The controller has DTR support, a bit must be set for it. The behaviour
is interesting though, as the speed won't improve when enabled. This is
because there seems to be an internal divisor (/2) which keeps the rate
equal when DTR is enabled. As a result, this commit also doubles the
target bus speed, which in practice does not happen. This way, there is
a real gain:
Before:
$ flash_speed /dev/mtd0 -dc10
eraseblock write speed is 1000 KiB/s
[...]
eraseblock read speed is 1199 KiB/s
[...]
After:
$ flash_speed /dev/mtd0 -dc10
eraseblock write speed is 985 KiB/s
[...]
eraseblock read speed is 1540 KiB/s

The speed setting is wrongly placed inside the "setup transfer" helper,
since the bus configuration may require the speed to be correct. Indeed,
DTR mode (not yet available) divides by 2 the bus clock when enabled. As
a result, to remain at a constant clock speed (and improve the data
rate), we must double the bus clock when enabling DTR. In order to
prepare for this change, move all the bus configuration required for
each step of the operation inside a unique helper called
nuvoton_qspi_configure_bus().

virtio_spi_probe() registers the SPI controller with
devm_spi_register_controller(). spi_register_controller() binds a child
inline unless its driver has asked for asynchronous probing, so a
peripheral that performs a transfer during its own probe reaches
virtio_spi_transfer_one(), which kicks the virtqueue before probe has
returned.
The driver never calls virtio_device_ready(), so DRIVER_OK is set on its
behalf by virtio_dev_probe(), only once probe has returned. The virtio
spec is explicit about that ordering in 3.1 Device Initialization:
| The driver MUST NOT send any buffer available notifications to the
| device before setting DRIVER_OK.
A device that waits for DRIVER_OK before servicing the queue therefore
leaves the transfer unanswered, and virtio_spi_transfer_one() waits for its
completion with no timeout, so probe never returns.
Mark the device ready before registering the controller, as done for the
same reason in commit f5866db64f34 ("virtio_console: enable VQs early") and
commit 1d774589f924 ("i2c: virtio: mark device ready before registering the
adapter").

With CONFIG_HWSPINLOCK=n the of_hwspin_lock_get_id() stub returns 0
unconditionally. In sprd_adi_probe() the guard
if (ret > 0 || (IS_ENABLED(CONFIG_HWSPINLOCK) && ret == 0))
is false for that 0, so it takes the else branch, where the switch has no
case for 0 and lands in
default:
return dev_err_probe(&pdev->dev, ret, "failed to find hwlock id\n");
dev_err_probe() returns its err argument unchanged, so probe logs
"failed to find hwlock id" and then returns 0, reporting success.
sprd_adi_hw_init(), the restart handler and devm_spi_register_controller()
are all skipped: the device binds but no SPI controller is ever
registered.
The hardware spinlock is optional for this controller and the -ENOENT arm
already covers "no hardware spinlock supplied". Treat the stub's 0 the
same way and continue without a lock; all four users of sadi->hwlock
already test it for NULL.
This is not reachable on production kernels. Kconfig has
depends on HWSPINLOCK || (COMPILE_TEST && !HWSPINLOCK)
so the affected configuration exists only under COMPILE_TEST, where no
real hardware is present.

DQS is a typical SPI memory signal used to help with reading the data on
the bus at high speeds (especially in DTR mode) by avoiding clock
skews. The chip generates a clock signal synchronized with its data
output fronts, also called data strobe.
SPI NOR and SPI NAND cores must set this flag in order to indicate to
other layers that DQS is available.
Create a getter and a setter to reach this capability.

At the same time, for pch_spi_pd_driver, we also switch to modern
driver.pm for pm ops.

Use the modern PM macros for the suspend and resume functions to be
automatically dropped by the compiler when CONFIG_PM or
CONFIG_PM_SLEEP are disabled, without having to use __maybe_unused.

Use the modern PM macros for the suspend and resume functions to be
automatically dropped by the compiler when CONFIG_PM or
CONFIG_PM_SLEEP are disabled, without having to use #ifdef guards or
__maybe_unused.
This has the advantage of always compiling these functions in,
independently of any Kconfig option. Thanks to that, bugs and other
regressions are subsequently easier to catch.
