2024-01-06PCI: dwc: Rename .func_conf_select to .get_dbi_offset in struct dw_pcie_ep_opsYoshihiro Shimoda
Since the struct member .func_conf_select makes the intentions behind it difficult to ascertain from its name alone, rename it to .get_dbi_offset to make the intended usage more obvious.

Add R-Car Gen4 PCIe controller support for host mode. This controller is based on Synopsys DesignWare PCIe. However, this particular controller has a number of vendor-specific registers, and as such, requires initialization code like mode setting and retraining and so on.
