Now that the SRAM readout code is fixed by using 32-bit accesses, it
always returns the same values as register readout, so the A64 variant
no longer needs the workaround. This makes the D1 variant structure
redundant, so remove it.

interconnect changes for 6.3

Here are the interconnect changes for the 6.3-rc1 merge window with the
significant part being new drivers.

Driver changes:
- New driver for Qualcomm SM8550
- New driver for Qualcomm QDU1000/QRU1000
- New driver for Qualcomm SDM670
- New driver for Qualcomm SA8775P
- Drop the IP0 interconnects and migrate them to RPMh clocks instead
- Misc improvements in the DT schema for some existing drivers

    turn up in additional SoCs going forwards.
* st,magn
  - Add support for magnetometer part of LSM303C which is very similar
    to standalone LIS3MDL already supported.
* ti,ads7924
  - New driver for this 4 channel, 12-bit I2C ADC.
* ti,lmp92064
  - New driver for this 12 bit SPI ADC.
* ti,tmag5273
  - New driver for this 3D Hall-Effect Sensor.

Features
* core
  - Add a standard structure for the value pairs in IIO_VAL_INT_PLUS_MICRO
    available attributes and similar.
* cirrus,ep93xx
  - Add DT binding docs and convert driver to DT based probing.
  - Enable testing building with CONFIG_COMPILE_TEST.
* st,stm32-dfsdm
  - Enable ID register support for discovery of hardware capabilities on
    some devices.

Cleanups and minor fixes
* core
  - Drop the custom iio_sysfs_match_string_with_gaps().
    The special ability of this function to skip gaps in an array
    was never used by any upstream driver.
  - Sort headers whilst touching this file.
* tools
  - Fix memory leak in iio_utils.c
* various
  - leftover i2c probe_new() conversions.
  - scnprintf() -> sysfs_emit() cleanups.
  - hand rolled devm enables -> devm_regulator[_bulk]_get_enable()
  - typo fixes
  - dt-binding cleanup (whitespace, excess quotes and similar)
* adi,ad7746
  - Set variable without pointless conditional.
* fsl,mma9551
  - Squash false positives about use of uninitialized variable where
    garbage undergoes an endian conversion before being ignored.
* measspec,ms5611
  - Switch to fully devm_ managed probe() and so drop explicit remove()
* qcom,spmi-adc
  - Use dev_err_probe() to suppress deferred print.
* qcom,spmi-adc5
  - Define a missing channel used for battery identification.
* qcom,spmi-iadc
  - Document a compatible seen in wild.
* semtech,sx9360
  - Fix units on semtech,resolution dt-binding.
* sensiron,scd30
  - dev_err_probe() usage to simplify error paths a little.
* st,lsm6dsx
  - Add missing mount matrix for the gyro IIO device.
* taos,tsl2563
  - Respect firmware configured interrupt polarity if present.
  - Use i2c_smbus_write_word_data() in a few cases not previously covered.
  - Factor out duplicated interrupt configuration.
  - Switch to GENMASK() / BIT() from hand coded equivalents.
  - Tidy up unused definitions.
  - Use dev_err_probe() as appropriate.
  - Drop platform_data as no in kernel users and there are better ways to
    do equivalent if any are added.
  - Add local struct device variable to tidy up code.
  - Avoid dance via i2c_client to get the drvdata.
  - Tidy up headers ordering and Makefile ordering.
* ti,adc128s052
  - Use new spi_get_device_match_data().
  - Drop ACPI_PTR() protection.
  - Sort headers whilst here.
  - Use asm instead of incorrect include of asm-generic/unaligned.h
* vishay,vcn4000
  - Interrupt support for vcnl4040 (lots of refactoring needed)
* xilinx,ams
  - Use fwnode_device_is_compatible() instead of open coding it.

MHI Host
========

- Fixed the module description

MHI Endpoint
============

- Powered down the MHI EP stack completely during MHI RESET instead of just
  doing transfer abort as the MMIO register access will be prohibited
  afterwards. EP stack will also be powered on again in case the RESET
  happened due to SYS_ERR.

- Added a sanity check before processing the command ring to make sure that
  the channel is supported by the controller.

- Added a check to make sure the xfer_cb is available for the channel
  before trying to send the error status to the client drivers. This
  helps in avoiding a potential null pointer dereference.

- Fixed the debug log of RESET command

- Modified the channel ring handler lock to protect the whole handler
  instead of locking it partially. This helps in avoiding a race that may
  happen if a channel STOP/RESET command is issued by the host parallely.

- Saved the MHI state locally during suspend and resume. Otherwise, the MHI
  EP stack will not be aware of a channel that got disabled and may try to
  access it later.

- Changed the MHI state_lock to mutex instead of spinlock. This helps in
  avoiding the sleeping in atomic bug reported by Dan Carpenter and also
  allows the lock to be held throughout the state change.

- Fixed the off by one error while doing the MHI channel check during
  command ring processing.

MHI Generic
===========

- Updated the MHI toplevel Makefile to use Kconfig flags for building the
  host and endpoint sub-directories conditionally.
