Add R-Car S4-8 (R-Car Gen4) PCIe Host and Endpoint support.
Changes from v1:
- Fix a lot of warning/errors by 'make DT_CHECKER_FLAGS=-m dt_binding_check'.
- Add PCI_EXP_LNKCAP_MLW macros into pci_regs.h
- Remove "extern" in pcie-rcar-gen4.h.
- Add ep_pre_init() into dw_pcie_ep_ops for this controller.
- Add a new flag "reset_all_bars" into dw_pcie_ep. If this way is acceptable,
I'll make patches for other endpoint controllers to simplify.
- Move timing of getting num-lanes property for {ep_pre,host}_init().
- Remove some platform_get_resource().
- Remove "struct rcar_gen4_pcie_ep".
- Allow a kernel module for both host and ep of this controller.
- Minor fixes for checkpatch.pl.
