The ad354xr requires DSPI mode (2 data lanes) to work in buffering
mode, so, depending on the DAC type, target TRANSFER_REGISTER
"MULTI_IO_MODE" bitfield can be set between:
SPI (configuration, entire ad35xxr family),
DSPI (ad354xr),
QSPI (ad355xr).
Also bus IO_MODE must be set accordingly.
About removal of AXI_DAC_CUSTOM_CTRL_SYNCED_TRANSFER, according to
the HDL history the flag has never been used. So looks like the driver
was including it by mistake or in anticipation for something that was
never implemented on HDL side.
Current HDL updated documentation confirm it is actually not in use
anymore and replaced by the IO_MODE bits.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
