Implement support for Exynos7870 USB DRD on top of the existing exynos5-usbdrd driver. Exynos7870 has a single USB 2.0 DRD PHY controller and no 3.0 PHYs. Thus, it only supports the UTMI interface. Moreover, the PMU register offset for enabling the PHY controller is different for SoCs such as Exynos7870, where BIT(0) is for the 3.0 PHY and BIT(1) is for the 2.0 PHY. The phy_isol function for Exynos7870 uses the appropriate register offsets.

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.
