This is a note to let you know that I've just added the patch titled
usb: dwc3: pci: Fix Bay Trail phy GPIO mappings
to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch.
The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.
If you have any questions about this process, please let me know.
From 62e3f0afe246720f7646eb1b034a6897dac34405 Mon Sep 17 00:00:00 2001 From: Hans de Goede hdegoede@redhat.com Date: Sun, 13 Feb 2022 14:05:17 +0100 Subject: usb: dwc3: pci: Fix Bay Trail phy GPIO mappings
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.
