From d026c96b25b7ce5df89526aad2df988d553edb4d Mon Sep 17 00:00:00 2001 From: Manu Gautam Date: Mon, 9 Dec 2019 16:15:01 +0100 Subject: [PATCH] arm64: dts: qcom: msm8996: Disable USB2 PHY suspend by core 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.
