From 33666516e74b471865d7f37834eba321dfe31f1c Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 22 Mar 2021 14:52:44 +0200 Subject: [PATCH] usb: dwc3: pci: Enable dis_uX_susphy_quirk for Intel Merrifield BugLink: https://bugs.launchpad.net/bugs/1923069 [ Upstream commit b522f830d35189e0283fa4d5b4b3ef8d7a78cfcb ] It seems that on Intel Merrifield platform the USB PHY shouldn't be suspended. Otherwise it can't be enabled by simply change the cable in the connector. Enable corresponding quirk for the platform in question.
