From 83e0190fb77c198fb9793200286dc815be91b12b Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sun, 13 Feb 2022 14:05:17 +0100 Subject: [PATCH] usb: dwc3: pci: Fix Bay Trail phy GPIO mappings commit 62e3f0afe246720f7646eb1b034a6897dac34405 upstream. When the Bay Trail phy GPIO mappings where added cs and reset were swapped, this did not cause any issues sofar, because sofar they were always driven high/low at the same time. Note the new mapping has been verified both in /sys/kernel/debug/gpio output on Android factory images on multiple devices, as well as in the schematics for some devices.
