9f7fb8de5d spi: Fixes for v5.17
There are quite a few fixes that have accumilated since the merge window
 here, all driver specific and none super urgent, plus a new device ID
 for the Rockchip driver.

282aa44c21 spi: Updates for v5.17
This has mostly been a quiet release for the SPI subsystem, almost all
 cleanups and fixes to existing drivers.  A couple of changes that stand
 out:
 
  - Cleanups and support for version specific features in the DesignWare
    controller.
  - Removal of support for Netlogic devices from the XLP driver, the
    platform had previously been removed by MIPS so the support couldn't
    be used.
  - Conversion of several DT bindings to YAML format.

spi: dt-bindings: add schema listing peripheral-specific properties
Many SPI controllers need to add properties to peripheral devices. This
could be the delay in clock or data lines, etc. These properties are
controller specific but need to be defined in the peripheral node
because they are per-peripheral and there can be multiple peripherals
attached to a controller.

If these properties are not added to the peripheral binding, then the
dtbs check emits a warning. But these properties do not make much sense
in the peripheral binding because they are controller-specific and they
will just pollute every peripheral binding. So this binding is added to
collect all such properties from all such controllers. Peripheral
bindings should simply refer to this binding and they should be rid of
the warnings.

There are some limitations with this approach. Firstly, there is no way
to specify required properties. The schema contains properties for all
controllers and there is no way to know which controller is being used.
Secondly, there is no way to restrict additional properties. Since this
schema will be used with an allOf operator, additionalProperties needs
to be true. In addition, the peripheral schema will have to set
unevaluatedProperties: false.

Despite these limitations, this appears to be the best solution to this
problem that doesn't involve modifying existing tools or schema specs.

Merge series "add support for Cadence's XSPI controller" from Parshuram Thombare <pthombar@cadence.com>:
This patch series adds support for Cadence's XSPI controller.
It supports 3 work modes.
1. ACMD (auto command) work mode
    ACMD name is because it uses auto command engine in the controller.
    It further has 2 modes PIO and CDMA (command DMA).
    The CDMA work mode is dedicated for high-performance application
    where very low software overhead is required. In this mode the
    Command Engine is programmed by the series of linked descriptors
    stored in system memory. These descriptors provide commands to execute
    and store status information for finished commands.
    The PIO mode work mode is dedicated for single operation where
    constructing a linked list of descriptors would require too
    much effort.
2. STIG (Software Triggered Instruction Generator) work mode
    In STIG mode, controller sends low-level instructions to memory.
    Each instruction is 128-bit width. There is special instruction
    DataSequence which carries information about data phase.
    Driver uses Slave DMA interface to transfer data as only this
    interface can be used in STIG work mode.
3. Direct work mode
    This work mode allows sending data without invoking any command through
    the slave interface.
Currently only STIG work mode is enabled, remaining work modes will
be added later.

Changes since v5:
1. Added adjust_op_size to adjust op size according to sdma size.

Changes since v4:
1. Changed reg region names and lengths as suggested by Rob.

Changes since v3:
1. Removed ACMD PIO mode.
2. Return IRQ_HANDLED only for handled interrupts.
3. DT binding changes.

Changes since v2:
1. Removed extra lock around exec_op.
2. Removed PHY parameters setting from the driver, those will be
   handled by bootstrap pins available in the controller.

Changes since v1:
1. Use ACMD PIO work mode for NOR read, program and erase operations,
   for everything else use STIG(Software Triggered Instruction
   Generator) work mode.
2. Changes suggested by Lukas.

spi: Use 'flash' node name instead of 'spi-flash' in example
Change the nodename in the example with spi-nand from 'spi-flash@1'
to 'flash@1' to make the schema uniform with both spi-nand and spi-nor
flashes. jedec,spi-nor.yaml uses 'flash@' nodename for spi-nor flashes,
so make the spi-nand examples in dt-bindings use it too for uniformity.

972d6a7dce dt-bindings: Drop redundant minItems/maxItems
If a property has an 'items' list, then a 'minItems' or 'maxItems' with the
same size as the list is redundant and can be dropped. Note that is DT
schema specific behavior and not standard json-schema behavior. The tooling
will fixup the final schema adding any unspecified minItems/maxItems.

This condition is partially checked with the meta-schema already, but
only if both 'minItems' and 'maxItems' are equal to the 'items' length.
An improved meta-schema is pending.
