 "Here is the big set of char/misc/android/iio and other small driver
  subsystem patches for 7.4-rc1. Loads of stuff in here, larger than
  normal. Highlights include:

   - removal of the C binder code, the rust version is stable and will
     be used going forward in a few billion devices. Great job by those
     developers

   - loads and loads of IIO driver updates and feature additions

   - speakup driver fixes and updates

   - mhi driver updates

   - mei driver updates

   - xillybus driver fixes

   - comedi driver fixes

   - lots of coresight driver updates

   - Interconnect driver updates

   - nvmem driver updates and fixes

   - slimbus driver updates and fixes

   - spmi driver updates and fixes

   - lots of tiny misc and char driver fixes based on people scanning
     for things

  All of these have been in linux-next for a while with no reported
  issues, other than a merge conflict with one of the rust tree files,
  which should be simple to resolve"

The QPIC SPI-NAND flash controller found on IPQ9650 is identical to the
one present on IPQ9574. Add the IPQ9650 compatible and use IPQ9574 as
the fallback.

The SPI and QSPI controllers use the same Devicetree node structure.
The additional SPI example only differs in property values and does not
demonstrate any binding-specific behavior.

Drop the redundant SPI example and keep the existing QSPI example.

Praveen Talari <praveen.talari@oss.qualcomm.com> says:

When operating in SPI target mode, the GENI controller relies on an
external GPIO to notify the SPI master about the target's active state.

Add support for an optional device GPIO that is asserted when a target
transfer begins and deasserted when the transfer completes, is aborted,
or hits a timeout. This allows the target to explicitly signal its
availability to the master and ensures the GPIO is released in all error
and completion paths, preventing the master from observing a stale or
incorrect target ready indication.

The ready GPIO is intentionally made optional and is requested only
when target mode is enabled. This preserves existing behaviour for
systems that do not require the signal and avoids regressions on
deployed platforms where the GPIO is already controlled from userspace.
Targets without a ready GPIO continue to operate unchanged by using
devm_gpiod_get_optional().

When operating in SPI target (slave) mode, the GENI SPI controller can
use an external GPIO to notify the SPI master about the target's
active state.

Document the optional ready-gpios property for the qcom,spi-geni-qcom
and qcom,sa8255p-geni-spi bindings, restricted to spi-slave nodes.

Convert the TI DaVinci/Keystone SPI controller binding from text format
to DT schema.

Changes during the conversion:
- Create a separate ti,davinci-spi-peripheral-props.yaml schema to
  properly define the ti,spi-wdelay peripheral property.
- Add missing dmas and dma-names properties.
- Add constraints to ti,spi-wdelay based on the 6-bit width
  of the SPIFMTn.WDELAY hardware register field.

Extend the existing MA35D1 QSPI binding to also describe the MA35D1 SPI
controller.

The SPI and QSPI controllers are separate hardware IPs. QSPI additionally
supports dual, quad and DTR transfers and a target-mode timeout function,
but these differences do not require additional controller-specific
Devicetree properties.

Both controllers expose the same Devicetree-visible resources and provide
up to two native chip-select signals. GPIO chip selects are supported
through the generic SPI controller binding. Since the MA35D1 QSPI driver
now supports GPIO chip selects, also remove the existing restriction
on cs-gpios for the QSPI compatible.

Add the nuvoton,ma35d1-spi compatible and update the binding description
and examples to cover both controllers.
