This adds a bunch of patches for the v6.1 Gemini kernel. For v5.15 this was down to a single upstream patch, but for kernel v6.2 I reworked the USB code for FOTG210, so instead of carrying over the half-baked and incomplete patch from v5.15 I just backported all the v6.2 patches, 31 in total, as it creates full device USB mode for e.g. D-Link DNS-313.

Subject: [PATCH 01/29] usb: phy: phy-gpio-vbus-usb: Add device tree probing
|
|
|
|
Make it possible to probe the GPIO VBUS detection driver
|
|
from the device tree compatible for GPIO USB B connectors.
|
|
|
|
Since this driver is using the "gpio-usb-b-connector"
|
|
compatible, it is important to discern it from the role
|
|
switch connector driver (which does not provide a phy),
|
|
so we add some Kconfig text and depend on !USB_CONN_GPIO.
