Krishna chaitanya chundru 29ff60fda5 PCI: qcom: Don't wait for link if we can detect Link Up
[ Upstream commit 36971d6c5a ]

If we have a 'global' IRQ for Link Up events, we need not wait for the
link to be up during PCI initialization, which reduces startup time.

Check for 'global' IRQ, and if present, set 'use_linkup_irq',
so dw_pcie_host_init() doesn't wait for the link to come up.

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.
