+Subject: [PATCH] dwc2: temporary force to be powered up all times
+
+the APM821xx's onchip dwc2 misbehaves with 5.4 and 5.10
+when a USB device gets connected. Instead of announcing
+and setting up the USB devices it crashes and burns with:
+
+[ 22.023476] dwc2 4bff80000.usbotg: dwc2_restore_global_registers: no global registers to restore
+[ 22.032245] dwc2 4bff80000.usbotg: dwc2_exit_partial_power_down: failed to restore registers
+[ 22.040647] dwc2 4bff80000.usbotg: exit partial_power_down failed
+[ 22.058765] dwc2 4bff80000.usbotg: HC died; cleaning up
+
+This is all seemingly fixed with dwc2 from a 5.16-rc6.
