Above mentioned patch is NOT the latest patch. Pratyush Anand already submitted the next patch as below. Tim, Would you test the following patch on i.MX6 platform? diff --git a/drivers/pci/host/pcie-designware.c b/drivers/pci/host/pcie-designware.c index be6ce30..b83f5e8 100644 --- a/drivers/pci/host/pcie-designware.c +++ b/drivers/pci/host/pcie-designware.c @@ -378,6 +378,7 @@ int __init dw_pcie_host_init(struct pcie_port *pp) + global_io_offset); pp->config.io_size = resource_size(&pp->io); pp->config.io_bus_addr = range.pci_addr; + pp->io_base = range.cpu_addr; } if (restype == IORESOURCE_MEM) { of_pci_range_to_resource(&range, np, &pp->mem); @@ -403,7 +404,6 @@ int __init dw_pcie_host_init(struct pcie_port *pp) pp->cfg0_base = pp->cfg.start; pp->cfg1_base = pp->cfg.start + pp->config.cfg0_size; - pp->io_base = pp->io.start; pp->mem_base = pp->mem.start; pp->va_cfg0_base = devm_ioremap(pp->dev, pp->cfg0_base, @@ -667,7 +667,7 @@ static int dw_pcie_setup(int nr, struct pci_sys_data *sys) if (global_io_offset < SZ_1M && pp->config.io_size > 0) { sys->io_offset = global_io_offset - pp->config.io_bus_addr; - pci_ioremap_io(sys->io_offset, pp->io.start); + pci_ioremap_io(global_io_offset, pp->io_base); global_io_offset += SZ_64K; pci_add_resource_offset(&sys->resources, &pp->io, sys->io_offset); Best regards, Jingoo Han -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
