Martin Blumenstingl bc4a0241d4 phy: amlogic: phy-meson-gxl-usb2: support the clock and reset line
The Meson GXL USB2 PHYs require an additional clock (USB) which has to
be enabled. If that clock is disabled then all PHY registers read 0x0.
Luckily for us that clock is always enabled (either by harddware
defaults, the bootrom, or any of the bootloaders before u-boot/BL3-3).

The OTG capable USB2 PHY additionally has a reset line (USB_OTG, which
is shared with other components, such as the USB3 PHY for example).

Extend the driver so it handles this clock and the shared reset line.
We only trigger the reset during the .init phase since it's a shared
reset line, so triggering it during the driver's .reset implementation
would effectively also only trigger it once anyways.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

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.
