-Subject: [PATCH] usb: xhci: Raspberry Pi FW loader for VIA VL805
-
-The VL805 FW may either be loaded from an SPI EEPROM or alternatively
-loaded directly by the VideoCore firmware. A PCI reset will reset
-the VL805 XHCI controller on the Raspberry Pi4 requiring the firmware
-to be reloaded if an SPI EEPROM is not present.
-
-Use a VideoCore mailbox to trigger the loading of the VL805
-firmware (if necessary) after a PCI reset.
