openwrt/target/linux/bcm27xx/patches-6.6/950-0796-dts-rp1-add-SNPS-quirk-to-USB3-host-controllers.patch
Álvaro Fernández Rojas 8c405cdccc bcm27xx: add 6.6 kernel patches
The patches were generated from the RPi repo with the following command:
git format-patch v6.6.34..rpi-6.1.y

Some patches needed rebasing and, as usual, the applied and reverted, wireless
drivers, Github workflows, READMEs and defconfigs patches were removed.

Subject: [PATCH 0796/1085] dts: rp1: add SNPS quirk to USB3 host controllers
Set snps,parkmode-disable-ss-quirk for usb0 and usb1.
Enabling this test/debug feature seems to prevent controller lockups
with bidirectional SS bulk endpoints active.
