We drop the fallback to the core driver due to compatibility issues. We add support for legacy interrupts for cards that lack MSI support (which is partially broken currently). We then add the device tree nodes to enable PCIe on the Quartz64 Model A. Patch 1 drops the snps,dw,pcie fallback from the dt-binding Patch 2 adds legacy interrupt support to the driver Patch 3 adds the device tree binding to the rk356x.dtsi Patch 4 enables the PCIe controller on the Quartz64-A Changelog: v5: - fix incorrect series (apologies for the v4 spam) v4: - drop the ITS modification, poor compatibility is better than completely broken v3: - drop select node from dt-binding - convert to for_each_set_bit - convert to generic_handle_domain_irq - drop unncessary dev_err - reorder irq_chip items - change to level_irq - install the handler after initializing the domain v2: - Define PCIE_CLIENT_INTR_STATUS_LEGACY - Fix PCIE_LEGACY_INT_ENABLE to only enable the RC interrupts - Add legacy interrupt enable/disable support *** BLURB HERE *** Peter Geis (4): dt-bindings: pci: remove fallback from Rockchip DesignWare binding PCI: dwc: rockchip: add legacy interrupt support arm64: dts: rockchip: add rk3568 pcie2x1 controller arm64: dts: rockchip: enable pcie controller on quartz64-a .../bindings/pci/rockchip-dw-pcie.yaml | 12 +- .../boot/dts/rockchip/rk3566-quartz64-a.dts | 34 ++++++ arch/arm64/boot/dts/rockchip/rk356x.dtsi | 55 +++++++++ drivers/pci/controller/dwc/pcie-dw-rockchip.c | 112 +++++++++++++++++- 4 files changed, 200 insertions(+), 13 deletions(-)
