Subject: [PATCH v11 00/13] PCI: rcar-gen4: Add R-Car Gen4 PCIe support
Date: Fri, 10 Mar 2023 21:34:57 +0900 [thread overview]
Message-ID: <20230310123510.675685-1-yoshihiro.shimoda.uh@renesas.com> (raw)
Add R-Car S4-8 (R-Car Gen4) PCIe Host and Endpoint support.
To support them, modify PCIe DesignWare common codes.
Patch [1/12] and [2/12] are bug fix patches.
Changes from v10:
https://patchwork.kernel.org/project/linux-pci/cover/20230308082352.491561-1-yoshihiro.shimoda.uh@renesas.com/
- Fix dt-bindings doc for endpoint (reported by Rob's bot).
- Add reg and reg-names to the dt-bindings doc of host.
- Fix examples in the dt-bindings docs of both host and endpoint.
- Add R-Car S4-8 device ID into the pci_test_endpoint driver.
Changes from v9:
https://lore.kernel.org/linux-pci/20230210134917.2909314-1-yoshihiro.shimoda.uh@renesas.com/
- Based on next-20230306
- Add bug fix patches into this patch series.
https://lore.kernel.org/linux-pci/20230216092012.3256440-1-yoshihiro.shimoda.uh@renesas.com/
https://lore.kernel.org/linux-pci/20230222015327.3585691-1-yoshihiro.shimoda.uh@renesas.com/
- Add maximum for max-link-speed and num-lanes to dt-bindings of both host and endpoint.
- Add max-functions to dt-bindings of endpoint.
- Use reg-names "app" on endpoint.
- Remove unnecessary linkup and wait process in rcar_gen4_pcie_host_init().
- Remove unnecessary macros in pcie-rcar-gen4.h.
- Use dbi2 to write BAR mask registers.
- Remove no_msix and intx_by_atu flags.
- Reduce __dw_pcie_prog_outbound_atu() arguments.
- Add dw_pcie_num_lanes_setup() to setup num_lanes.
- Refactor dw_pcie_setup() to avoid PCIE_PORT_LINK_CONTROL writing twice.
