PCI: eswin: Add ESWIN PCIe Root Complex driver

2026-03-19T21:40:03+00:00

Add driver for the ESWIN PCIe Root Complex based on the DesignWare PCIe core, IP revision 5.96a. The PCIe Gen.3 Root Complex supports data rate of 8 GT/s and x4 lanes, with INTx and MSI interrupt capability.

PCI/pwrctrl: generic: Rename pci-pwrctrl-slot as generic

2026-03-18T17:10:51+00:00

The driver is pretty generic and would fit for either PCI Slots or endpoints connected to PCI ports, so rename the driver and module as pci-pwrctrl-generic.

PCI: qilai: Add Andes QiLai SoC PCIe host driver support

2026-03-05T06:24:48+00:00

Add driver support for DesignWare based PCIe controller in Andes QiLai SoC. The driver only supports the Root Complex mode.

PCI: dwc: Remove not-going-to-be-supported code for Baikal SoC

2026-03-02T14:10:35+00:00

As noticed in the discussion [1] the Baikal SoC and platforms are not going to be finalized, hence remove stale code.

PCI: layerscape: Allow to compile as module

2026-02-26T06:03:43+00:00

The layerscape pcie host controller could also be compiled as module. Add the necessary infrastructure to allow building as module instead of only as builtin driver. Since the driver doesn't expose an irqchip controller, it is also safe to be removed during runtime.

PCI: dwc: tegra194: Broaden architecture dependency

2026-01-08T04:25:00+00:00

Replace ARCH_TEGRA_194_SOC dependency with a more generic ARCH_TEGRA check for the Tegra194 PCIe controller, allowing it to be built on Tegra platforms beyond Tegra194. Additionally, ensure compatibility by requiring ARM64 or COMPILE_TEST since this driver works only for ARM64 Tegra SoCs.
