Patch 2/5 is the only one that affect platforms different from Hisilicon The only difference between V3 patch[2/5] and v2 patch[2/4] is ************* diff --git a/drivers/pci/host/pci-keystone-dw.c b/drivers/pci/host/pci-keystone-dw.c index f34892e..b1e4135 100644 --- a/drivers/pci/host/pci-keystone-dw.c +++ b/drivers/pci/host/pci-keystone-dw.c @@ -327,7 +327,7 @@ static void ks_dw_pcie_clear_dbi_mode(void __iomem *reg_virt) void ks_dw_pcie_setup_rc_app_regs(struct keystone_pcie *ks_pcie) { struct pcie_port *pp = &ks_pcie->pp; - u32 start = pp->mem.start, end = pp->mem.end; + u32 start = pp->mem->start, end = pp->mem->end; int i, tr_size; /* Disable BARs for inbound access */ ************** That is present in v3 but not in v2.
