[ Upstream commit5eda42aebb] The function mxs_phy_is_otg_host() will return true if OTG_ID_VALUE is 0 at USBPHY_CTRL register. However, OTG_ID_VALUE will not reflect the real state if the ID pin is float, such as Host-only or Type-C cases. The value of OTG_ID_VALUE is always 1 which means device mode. This patch will fix the issue by judging the current mode based on last_event. The controller will update last_event in time.

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.
