From: Jiaqing Zhao <jiaqing.zhao@xxxxxxxxxxxxxxx> commit 16aae4c64600a6319a6f10dbff833fa198bf9599 upstream. The PCI function 2 on ASIX AX99100 PCIe to Multi I/O Controller can be configured as a single-port parallel port controller. The subvendor id is 0x2000 when configured as parallel port. It supports IEEE-1284 EPP / ECP with its ECR on BAR1.
