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"

+What:		/sys/class/spi_master/spiB/new_device
+Date:		July 2026
+KernelVersion:	7.3
+Contact:	linux-spi@vger.kernel.org
+Description:	(WO) Instantiate a new SPI device on bus B, where B
+		is the bus number (0, 1, 2, ...). Takes parameters
+		in the format:
+
+		<modalias> <chip_select> [<max_speed_hz> [<mode>]]
+
+		where modalias is the driver name, chip_select is the
+		CS line number, and max_speed_hz and mode are optional.
+
+		The device can later be removed with delete_device.
+
+		Only devices created via this interface can be removed
+		with delete_device; platform and DT devices are not
+		affected.
+
+		Example:
+		# echo spidev 0 > /sys/class/spi_master/spi0/new_device
+		# echo spidev 0 10000000 > /sys/class/spi_master/spi0/new_device
+		# echo spidev 0 10000000 3 > /sys/class/spi_master/spi0/new_device
+
+What:		/sys/class/spi_master/spiB/delete_device
+Date:		July 2026
+KernelVersion:	7.3
+Contact:	linux-spi@vger.kernel.org
+Description:	(WO) Remove a SPI device previously created via
+		new_device. Takes a single parameter: the chip select
+		number of the device to remove.
+
+		Example:
+		# echo 0 > /sys/class/spi_master/spi0/delete_device
