Merge tag 'spi-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi updates from Mark Brown: "The diffstat for this release is dominated by the new Airoha driver, mainly as a result of this being a generally quite quiet release. There were a couple of cleanups in the core but nothing substantial, the updates here are almost all driver specific ones. - Support for multi-word mode in the OMAP2 McSPI driver - Overhaul of the PXA2xx driver, mostly API updates - A number of DT binding conversions - Support for Airoha NAND controllers, Cirrus Logic CS35L56, Mobileye EYEQ5 and Renesas R8A779H0" * tag 'spi-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (87 commits) spi: dw: Bail out early on unsupported target mode spi: Remove unneded check for orig_nents MAINTAINERS: repair file entry in AIROHA SPI SNFI DRIVER spi: pxa2xx: Drop the stale entry in documentation TOC spi: pxa2xx: Don't provide struct chip_data for others spi: pxa2xx: Remove timeout field from struct chip_data spi: pxa2xx: Remove DMA parameters from struct chip_data spi: pxa2xx: Drop struct pxa2xx_spi_chip spi: pxa2xx: Don't use "proxy" headers spi: pxa2xx: Remove outdated documentation spi: pxa2xx: Move contents of linux/spi/pxa2xx_spi.h to a local one spi: pxa2xx: Provide num-cs for Sharp PDAs via device properties spi: pxa2xx: Allow number of chip select pins to be read from property spi: dt-bindings: ti,qspi: convert to dtschema spi: bitbang: Add missing MODULE_DESCRIPTION() spi: bitbang: Use NSEC_PER_*SEC rather than hard coding spi: dw: Drop default number of CS setting spi: dw: Convert dw_spi::num_cs to u32 spi: dw: Add a number of native CS auto-detection spi: dw: Convert to using BITS_TO_BYTES() macro ...

-* Marvell Armada 3700 SPI Controller

-Required Properties:
-
-- compatible: should be "marvell,armada-3700-spi"
-- reg: physical base address of the controller and length of memory mapped
- region.
-- interrupts: The interrupt number. The interrupt specifier format depends on
- the interrupt controller and of its driver.
-- clocks: Must contain the clock source, usually from the North Bridge clocks.
-- num-cs: The number of chip selects that is supported by this SPI Controller
-- #address-cells: should be 1.
-- #size-cells: should be 0.

-TI QSPI controller.
-
-Required properties:
-- compatible : should be "ti,dra7xxx-qspi" or "ti,am4372-qspi".
-- reg: Should contain QSPI registers location and length.
-- reg-names: Should contain the resource reg names.
- - qspi_base: Qspi configuration register Address space
- - qspi_mmap: Memory mapped Address space
- - (optional) qspi_ctrlmod: Control module Address space
-- interrupts: should contain the qspi interrupt number.
-- #address-cells, #size-cells : Must be present if the device has sub-nodes
-- ti,hwmods: Name of the hwmod associated to the QSPI
-
-Recommended properties:
-- spi-max-frequency: Definition as per
- Documentation/devicetree/bindings/spi/spi-bus.txt
-
-Optional properties:
-- syscon-chipselects: Handle to system control region contains QSPI
- chipselect register and offset of that register.
-
-NOTE: TI QSPI controller requires different pinmux and IODelay
-parameters for Mode-0 and Mode-3 operations, which needs to be set up by
-the bootloader (U-Boot). Default configuration only supports Mode-0
-operation. Hence, "spi-cpol" and "spi-cpha" DT properties cannot be
-specified in the slave nodes of TI QSPI controller without appropriate
-modification to bootloader.
-
-Example:
-
-For am4372:
-qspi: qspi@47900000 {
- compatible = "ti,am4372-qspi";
- reg = <0x47900000 0x100>, <0x30000000 0x4000000>;
- reg-names = "qspi_base", "qspi_mmap";
- #address-cells = <1>;
- #size-cells = <0>;
- spi-max-frequency = <25000000>;
- ti,hwmods = "qspi";
-};
-
-For dra7xx:
-qspi: qspi@4b300000 {
- compatible = "ti,dra7xxx-qspi";
- reg = <0x4b300000 0x100>,
