The ast2600 i3c hardware is capable of IBIs, but we need a workaround for a hardware issue with the I3C state machine handling IBI payloads of specific lengths when PEC is not enabled. To avoid this, we need to unconditionally enable PECs, at the consquence of losing a byte of data when the device does not send a PEC. Enable IBIs on the ast2600 platform, including an implementation of the PEC workaround, which prints a warning when triggered.

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.
