From a5d847b0afd317df1ed0e3b72fbef72ce4824532 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sun, 13 Feb 2022 14:05:20 +0100 Subject: [PATCH] usb: dwc3: pci: Also apply Bay Trail GPIO mappings to ulpi-device In order for the phy driver to be able to actually get and control the cs and reset GPIOs the dev_id member of the gpiod_lookup table must be set to point to the dev_name() of the ulpi-device instantiated by dwc3_ulpi_init().
