MIPI I3C HCI specification v1.1 describes the ENTRY_SIZE field for the Device Address Table (DAT) and the Device Characteristics Table (DCT) section offset registers (DAT_SECTION_OFFSET and DCT_SECTION_OFFSET). That field is not documented in earlier version. ENTRY_SIZE value 0 is meant to be backward compatible. For the DAT entry size it is interpreted as 2 DWORDs (8-bytes) and for the DCT entry size as 4 DWORDs (16-bytes). Values 1-15 are reserved for future use. New version I believe fixes also the TABLE_SIZE field description. Before it was defined in DWORDs which I believe is incorrect since the DAT/DCT table entry structures, and sizes, are described having 8-bytes/16-bytes entries. This is more clear in the specification v1.1 which states the TABLE_SIZE fields are interpreted as number of entries in the DAT/DCT tables. I believe this same holds also in earlier version, at least it makes more sense. Fix code accordingly and let the DAT_entry_size and the DCT_entry_size variables carry the size as bytes. Which is how it is already interpreted in the dat_v1.c: hci_dat_v1_init().

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 Restructured Text 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.
