Move i2c locking primitives to request_locality and relinquish_locality callbacks, what effectively blocks TPM bus for the whole duration of logical TPM operation. With this in place, cr50-equipped TPM may be shared with external CPUs - assuming that underneath i2c controller driver is aware of this setup (see i2c-designware-amdpsp as an example).

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.
