Merge tag 'spi-v7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

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
instantiating devices from sysfs similarly to how it's already done
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
development boards with non-enumerable plugin modules, from
Vishwaroop A.

- Support for DQS in spi-mem, an additional signal used by flash
devices to avoid clock skew from Miquel Raynal.

- Support for more advanced SPI modes on DesignWare controllers from
Sudip Mukherjee.

- Changes from Jisheng Zhang to update to modern methods of
specifying the PM callbacks.

- Fixes for DMA mapping error handling, plus KUnit tests for this,
from Honghui Jiang.

- Substantial cleanup and performance work in the nxp-spi driver.

- Support for Microchip LAN969x, Nuvoton MA35D1 QSPI, Qualcomm
SA8255p and SA8797P, and StarFive JHB100 SFC"

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.
