It's normal to have the DW PCIe RP/EP DT-nodes equipped with the explicit
PHY phandle references. There can be up to 16 PHYs attach in accordance
with the maximum number of supported PCIe lanes. Let's extend the common
DW PCIe controller schema with the 'phys' and 'phy-names' properties
definition. There two types PHY names are defined: preferred generic names
'^pcie[0-9]+$' and non-preferred vendor-specific names
'^pcie([0-9]+|-?phy[0-9]*)?$' so to match the names currently supported by
the DW PCIe platform drivers ("pcie": meson; "pciephy": qcom, imx6;
"pcie-phy": uniphier, rockchip, spear13xx; "pcie": intel-gw; "pcie-phy%d":
keystone, dra7xx; "pcie": histb, etc).

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.
