Hi!

commit 2a6d0d63d99956a66f6605832f11755d74a41951 upstream.

Add support for R-Car PCIe controller to work in endpoint mode.

+ ep->ob_window[i].phys_base = res->start;
+ ep->ob_window[i].size = resource_size(res);
+ /* controller doesn't support multiple allocation
+ * from same window, so set page_size to window size
+ */

Comment not according to CodingStyle.

+ memset(&win, 0x0, sizeof(win));
+ memset(&res, 0x0, sizeof(res));

Plain 0 would be enough

+ val |= ASTINTX;
+ rcar_pci_write_reg(pcie, val, PCIEINTXR);
+ usleep_range(1000, 1001);
+ val = rcar_pci_read_reg(pcie, PCIEINTXR);

This is crazy. Either you need exact timing or you don't, but I don't
believe usleep can guarantee microsecond accuracy.

(And you probably don't need it, right?)

Best regards,
Pavel
