As per DWC PCIe UM, ELBI delivers an inbound register RD/WR received by the controller to external application registers when the controller is expected to generate the PCIe completion of this register RD/WR. In this driver register space which is currently marked as ELBI, is not used for this purpose (Not sure why original author has named this set of registers as ELBI) So to keep this technically correct, it should be marked as application specific wrapper register space. We used name as "appl" taking reference from intel-gw-pcie.yaml's similar register space named as "app", whereas in nvidia,tegra194-pcie.yaml it's named "appl". So our argument is if a future Samsung manufactured SoC having DWC PCIe controller comes with support of real ELBI interface, we need to use the name elbi. We know such SoC exists but they are not yet upstreamed. Ready to adopt the best possible suggested method to make this happen but I really think the name ELBI is misleading. > > Best regards, > Krzysztof _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
