When docked to a Motorola lapdock or media dock, we're in USB A-host mode with VBUS provided by the dock. When in regular USB A-host mode, we're providing the VBUS. And in regular USB A-host mode we must also keep kicking the VBUS to keep it active. Let's wait a bit before configuring the USB PHY to allow some time between the ID and VBUS changes. And let's add vbus_provider flag so we can detect docked mode and regularo USB A-host mode better. With better USB A-host mode detection, we can now also just kick the VBUS to keep it enabled and leave out the unnecessary line muxing. We only need to set and clear vbus_provider in the delayed work so no locking is needed for it currently.

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.
