[ Upstream commit d026c96b25b7ce5df89526aad2df988d553edb4d ] QUSB2 PHY on msm8996 doesn't work well when autosuspend by dwc3 core using USB2PHYCFG register is enabled. One of the issue seen is that PHY driver reports PLL lock failure and fails phy_init() if dwc3 core has USB2 PHY suspend enabled. Fix this by using quirks to disable USB2 PHY LPM/suspend and dwc3 core already takes care of explicitly suspending PHY during suspend if quirks are specified.

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.
