spi: mtk-nor: Propagate errors from optional IRQ lookup
platform_get_irq_optional() returns a positive IRQ number on success or
a negative error code on failure. For an optional IRQ, -ENXIO indicates
that no IRQ is available, while other errors should be propagated.

Propagate errors such as -EPROBE_DEFER and -EINVAL instead of continuing
probe without the IRQ.

Add quad mode support for QPIC SNAND
Md Sadre Alam <md.alam@oss.qualcomm.com> says:

The Qualcomm QPIC SPI-NAND controller supports both single (x1) and
quad (x4) transfer modes, however the current driver operates only in
single-bit mode. This series adds support for quad data transfers and
includes a vendor-specific fix required for Macronix SPI-NAND devices.

spi: spi-qpic-snand: Handle Macronix quad read opcode 0x6b
Macronix SPI-NAND devices use opcode 0x6b for quad output cache reads,
while most other devices use opcode 0xeb. The QPIC SPI-NAND driver does
not currently recognize opcode 0x6b, causing read operations to fail
when Macronix devices select this cache read variant.

Add the Macronix-specific read opcode to the command mapping logic and
treat it the same as the existing quad read operations.

This allows Macronix SPI-NAND devices to operate correctly in quad read
mode.

spi: spi-qpic-snand: add quad mode support
Add support for quad (x4) transfer mode in the QPIC SPI NAND driver.
The controller supports both single (x1) and quad (x4) SPI transfers,
but the driver currently operates only in x1 mode.

Track the QUAD enable state from the device configuration register
(0xB0) and switch the data transfer width accordingly. When the core
enables quad mode, use x4 transfers for read and program operations to
improve throughput.

Introduce a quad_mode flag in struct qpic_spi_nand to cache the current
device state. The flag is updated based on GET_FEATURE responses from
the configuration register.

platform_get_irq_optional() returns a positive IRQ number on success or
a negative error code on failure. For an optional IRQ, -ENXIO indicates
that no IRQ is available, while other errors should be propagated.

Instead of only checking for -EPROBE_DEFER, propagate all error codes
returned by platform_get_irq_optional() other than -ENXIO, so that
failures are properly reported to the caller.

spi: sprd-adi: Fix probe succeeding without registering the controller
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.

Found by smatch:
drivers/spi/spi-sprd-adi.c:560 sprd_adi_probe() warn: passing zero to 'dev_err_probe'

spi: spi-mem: Flag DQS capability
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.

spi: fsl-espi: use modern PM macros
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.

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.

spi: add new_device/delete_device sysfs interface
Vishwaroop A <va@nvidia.com> says:

Add I2C-style new_device/delete_device sysfs attributes to SPI host
controllers, allowing userspace to instantiate and remove SPI devices
at runtime without device-tree changes.

Patch 1 adds the new_device/delete_device attributes and the supporting
infrastructure (userspace_clients list, manual sysfs group registration).
Patch 2 adds the ABI and user-facing documentation.
