Introduce power management ops supported by the TISCI Low Power Mode API [1]. 1) TISCI_MSG_LPM_WAKE_REASON Get which wake up source woke the SoC from Low Power Mode. The wake up source IDs will be common for all K3 platforms. 2) TISCI_MSG_LPM_SET_DEVICE_CONSTRAINT Set LPM constraint on behalf of a device. By setting a constraint, the device ensures that it will not be powered off or reset in the selected mode. 3) TISCI_MSG_LPM_SET_LATENCY_CONSTRAINT Set LPM resume latency constraint. By setting a constraint, the host ensures that the resume time from selected mode will be less than the constraint value.

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.
