From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx> Hi, Series adds a PCIe driver for the Renesas RZ/G3S SoC. It is split as follows: - patches 1-2/6: add PCIe support for the RZ/G3S SoC - patches 3-6/6: add device tree support and defconfig flag Please provide your feedback. Merge strategy, if any: - patches 1-2/6 can go through the PCI tree - patches 3-6/6 can go through the Renesas tree Thank you, Claudiu Beznea Changes in v4: - dropped v3 patches: - "clk: renesas: r9a08g045: Add clocks and resets support for PCIe" - "soc: renesas: rz-sysc: Add syscon/regmap support" as they are already integrated - dropped v3 patch "PCI: of_property: Restore the arguments of the next level parent" as it is not needed anymore in this version due port being added in device tree - addressed review comments - per-patch changes are described in each individual patch Changes in v3: - added patch "PCI: of_property: Restore the arguments of the next level parent" to fix the legacy interrupt request - addressed review comments - per-patch changes are described in each individual patch Changes in v2: - dropped "of/irq: Export of_irq_count()" as it is not needed anymore in this version - added "arm64: dts: renesas: rzg3s-smarc-som: Update dma-ranges for PCIe" to reflect the board specific memory constraints - addressed review comments - updated patch "soc: renesas: rz-sysc: Add syscon/regmap support" - per-patch changes are described in each individual patch Claudiu Beznea (6): dt-bindings: PCI: renesas,r9a08g045s33-pcie: Add documentation for the PCIe IP on Renesas RZ/G3S PCI: rzg3s-host: Add Renesas RZ/G3S SoC host driver arm64: dts: renesas: r9a08g045: Add PCIe node arm64: dts: renesas: rzg3s-smarc-som: Update dma-ranges for PCIe arm64: dts: renesas: rzg3s-smarc: Enable PCIe arm64: defconfig: Enable PCIe for the Renesas RZ/G3S SoC .../bindings/pci/renesas,r9a08g045-pcie.yaml | 240 +++ MAINTAINERS | 8 + arch/arm64/boot/dts/renesas/r9a08g045.dtsi | 66 + .../boot/dts/renesas/rzg3s-smarc-som.dtsi | 10 + arch/arm64/boot/dts/renesas/rzg3s-smarc.dtsi | 11 + arch/arm64/configs/defconfig | 1 + drivers/pci/controller/Kconfig | 8 + drivers/pci/controller/Makefile | 1 + drivers/pci/controller/pcie-rzg3s-host.c | 1792 +++++++++++++++++ 9 files changed, 2137 insertions(+) create mode 100644 Documentation/devicetree/bindings/pci/renesas,r9a08g045-pcie.yaml create mode 100644 drivers/pci/controller/pcie-rzg3s-host.c -- 2.43.0
