Implement get_name() interface of spi_controller_mem_ops so as to avoid
changing of mtd->name due to driver being moved over to spi-mem
framework from SPI NOR. This avoids breaking of MTD cmdline args being
passed by bootloaders which maybe using old driver name.

The caller of stm32_spi_transfer_one(), spi_transfer_one_message(),
is waiting for us to call spi_finalize_current_transfer() and will
eventually schedule a new transfer, if available.

before calling spi_finalize_current_transfer().

Previously the stm32h7 interrupt thread cleared all non-masked interrupts.
If an interrupt was to occur during the handling of another interrupt its
flag would be unset, resulting in a lost interrupt.

flags.

CONFIG_OF_DYNAMIC and CONFIG_ACPI allow adding SPI devices at runtime
using a DeviceTree overlay or DSDT patch.  CONFIG_SPI_SLAVE allows the
same via sysfs.

But there are no precautions to prevent adding a device below a
controller that's being removed.  Such a device is unusable and may not
even be able to unbind cleanly as it becomes inaccessible once the
controller has been torn down.  E.g. it is then impossible to quiesce
the device's interrupt.

of_spi_notify() and acpi_spi_notify() do hold a ref on the controller,
but otherwise run lockless against spi_unregister_controller().

Fix by holding the spi_add_lock in spi_unregister_controller() and
bailing out of spi_add_device() if the controller has been unregistered
concurrently.

Before generic upgrade, both .suspend() and .resume() were invoking
pci_enable_wake(pci_dev, PCI_D3hot, 0). Hence, disabling wakeup in both
states. (Normal trend is .suspend() enables and .resume() disables the
wakeup.)

This was ambiguous and may be buggy. Instead of replicating the legacy
behavior, drop the wakeup-disable call.

Simply copying all xfers from userspace into one bounce buffer causes
alignment problems if the SPI controller uses DMA.

Ensure that all transfer data blocks within the rx and tx bounce buffers
are aligned for DMA (according to ARCH_KMALLOC_MINALIGN).

Alignment may increase the usage of the bounce buffers. In some cases,
the buffers may need to be increased using the "bufsiz" module
parameter.

Drivers using legacy PM have to manage PCI states and device's PM states
themselves. They also need to take care of configuration registers.

With improved and powerful support of generic PM, PCI Core takes care of
above mentioned, device-independent, jobs.

This driver makes use of PCI helper functions like
pci_save/restore_state(), pci_enable/disable_device(), pci_enable_wake()
and pci_set_power_state() to do required operations. In generic mode, they
are no longer needed.

Change function parameter in both .suspend() and .resume() to
"struct device*" type. Use dev_get_drvdata() to get drv data.

This converts the PPC4xx SPI driver to use GPIO descriptors.

The driver is already just picking some GPIOs from the device
tree so the conversion is pretty straight forward. However
this driver is looking form a pure "gpios" property rather
than the standard binding "cs-gpios" so we need to add a new
exception to the gpiolib OF parser to allow this for this
driver's compatibles.

Call the put function after probe successfully. Otherwise, the lpspi
module will keep active status until the first spi transfer called.

Disable runtime pm when probe fails. There is no need to active runtime
pm after probe failed.

Since ACPI_PTR() is used to NULLify the value when !CONFIG_ACPI,
struct 'spi_acpi_match' becomes defined but unused.

Fixes the following W=1 kernel build warning(s):

 drivers/spi/spi-amd.c:297:36: warning: ‘spi_acpi_match’ defined but not used [-Wunused-const-variable=]
 297 | static const struct acpi_device_id spi_acpi_match[] = {
