pci: pcie-rcar-gen4: Switch to devm_*() GPIO and reset

2026-08-20T18:15:23Z

Use device managed GPIO and reset get to automatically free those resources up. No functional change. Signed-off-by: Marek Vasut

pci: pcie-rcar-gen4: Avoid repeated link attempts

2026-08-20T18:15:23Z

Avoid repeated link attempts for these controllers. In case the controller link is up, this is a noop since the probe() already finished. In case the controller link is down, a repeated link up attempt seems to require reset of both PCIe controllers, which is not desired. It is also unlikely that a repeated link attempt would bring the link up, as U-Boot does not support hotplug anyway. Therefore, prevent repeated link attempts. Signed-off-by: Marek Vasut

pci: pcie-rcar-gen4: Switch to generic firmware loader

2026-08-20T18:15:23Z

Use generic request_firmware_into_buf_via_script() instead of local implementation of similar functionality. This reduces code duplication. Signed-off-by: Marek Vasut

pci: layerscape: fix pci_iommu_extra hotplug

2026-08-11T07:48:22Z

We can have many pci hotplug groups, each introduced by a "pci@" token such as, pci_iommu_extra=pci@0x3600000,1.0.0,hp,pci@0x3700000,1.0.0,hp, pci@0x3800000,1.0.0,hp,pci@0x3900000,1.0.0,hp Without this fix, we have the error: Added iommu map for hotplug 1.0.0 ERROR: invalid action in extra iommu entry ERROR: invalid action in extra iommu entry ERROR: invalid action in extra iommu entry Fixes: 2a5bbb13cc39 ("pci: layerscape: add a way of specifying additional iommu mappings") Signed-off-by: Vincent Jardin Reviewed-by: Neil Armstrong Signed-off-by: Peng Fan

pci: pcie-rcar-gen4: Handle always on reference clock

2026-08-02T20:15:37Z

The clock controller driver for the device which supplies reference clock to the PCIe core and bus may not implement .enable / .disable callbacks in case the clock supplied by the device are always on, in which case the clk_prepare_enable() call returns -ENOSYS. This is the case on e.g. 9FGV0441. Handle the -ENOSYS as a valid return value and proceed with probing. Signed-off-by: Marek Vasut

pci: layerscape: ep: Use dev APIs

2026-07-01T09:42:52Z

Convert the Layerscape PCIe endpoint driver to use device and ofnode-based APIs instead of legacy FDT interfaces. Replace devfdt_get_addr_index_ptr(), fdt_get_named_resource(), fdtdec_get_bool(), and fdtdec_get_int() with their modern counterparts such as dev_read_addr_index_ptr(), dev_read_resource_byname(), dev_read_bool(), and dev_read_s32_default(). Also remove the dependency on gd->fdt_blob and global data access. No functional changes.

pci: mpc85xx: Simplfy code with dev_remap_addr()

2026-07-01T09:42:51Z

devfdt_get_addr_ptr() + map_physmem() could be simplifed with devfdt_remap_addr(). But to avoid direct dependency on devfdt_* helpers, use dev_remap_addr(). No functional changes.
