When adding runtime PM support to the Tegra XHCI driver, it is desirable to move the function calls to enable the clocks, regulators and PHY from the tegra_xusb_probe into the runtime PM handlers. Currently, the clocks, regulators and PHY are all enabled before we call usb_create_hcd() in tegra_xusb_probe(), however, we cannot call pm_runtime_get_sync() at this point because the platform device data is not yet initialised. Fortunately, the function usb_create_hcd() can be called before we enable the clocks, regulators and PHY and so prepare for adding runtime PM support, by moving the call to usb_create_hcd() before we enable the hardware.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
