Linux kernel source tree
26c9d152eb
A significant number of Trusted Platform Modules conform to the "TIS"
specification published by the Trusted Computing Group ("TCG PC Client
Specific TPM Interface Specification"). These chips typically use an
SPI, I²C or LPC bus as transport (via MMIO in the latter case). Some
of them even support multiple of those buses (selectable through a
config strap) or the same chip is available in multiple SKUs, each with
a different bus interface.
The devicetree bindings for these TPMs have not been converted to DT
schema yet and are spread out across 3 generic files and 2 chip-specific
files. A few TPM compatible strings were added to trivial-devices.yaml
even though additional properties are documented in the plaintext
bindings.
Consolidate the devicetree bindings into 3 yaml files, one per bus.
Move common properties to a separate tpm-common.yaml.
Document compatible strings which are supported by the TPM TIS driver
but were neglected to be added to the devicetree bindings.

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.
