It also implements other functions, including a reset and clock controller, an address translation unit, and a few other devices. PCIe BARs provide access to registers that manage these IP blocks, and the SoC is modeled using a PCI endpoint bus in devicetree. This allows the IP blocks to be bound to platform drivers using MMIO through the PCI BARs. This series introduces the simple PCI driver necessary to implement the PCI endpoint bus. It enables the device, enables master access, and then scans the devicetree subnodes to discover any devices defined within the endpoint buses. -Alex Note: to work correctly, this series depends on this: https://lore.kernel.org/lkml/20260813220717.1394644-1-elder@riscstar.com/ Alex Elder (2): dt-bindings: misc: introduce pci1179,0220.yaml misc: tc9564: introduce base PCI driver .../bindings/misc/pci1179,0220.yaml | 150 ++++++++++++++++++ MAINTAINERS | 7 + drivers/misc/Kconfig | 10 ++ drivers/misc/Makefile | 1 + drivers/misc/tc9564-pci.c | 89 +++++++++++ drivers/pci/quirks.c | 1 + 6 files changed, 258 insertions(+) create mode 100644 Documentation/devicetree/bindings/misc/pci1179,0220.yaml create mode 100644 drivers/misc/tc9564-pci.c base-commit: 5e6de6a2b522f659defacb1551d0465ba6ce13cf -- 2.53.0
