If anyone has any objections, please let me know. ------------------ From: Niklas Cassel [ Upstream commit ec9fd499b9c60a187ac8d6414c3c343c77d32e42 ] The Root Complex specific device tree binding for pcie-dw-rockchip has the 'sys' interrupt marked as required. The driver requests the 'sys' IRQ unconditionally, and errors out if not provided. Thus, we can unconditionally set 'use_linkup_irq', so dw_pcie_host_init() doesn't wait for the link to come up. This will skip the wait for link up (since the bus will be enumerated once the link up IRQ is triggered), which reduces the bootup time.
