2024-08-09	dt-bindings: PCI: host-generic-pci: Drop minItems and maxItems of ranges	Frank Li
	The ranges description states that "at least one non-prefetchable memory and one or both of prefetchable memory and IO space may also be provided." However, it should not limit the maximum number of ranges to 3. Freescale LS1028 and iMX95 use more than 3 ranges because the space splits some discontinuous prefetchable and non-prefetchable segments. Drop minItems and maxItems. The number of entries will be limited to 32 in pci-bus-common.yaml in dtschema, which should be sufficient. Fixes this CHECK_DTBS warning: arch/arm64/boot/dts/freescale/fsl-ls1028a-rdb.dtb: pcie@1f0000000: ranges: [[2181038080, 1, 4160749568, 1, 4160749568, 0, 1441792], [3254779904, 1, 4162191360, 1, 4162191360, 0, 458752], [2181038080, 1, 4162650112, 1, 4162650112, 0, 131072], [3254779904, 1, 4162781184, 1, 4162781184, 0, 131072], [2181038080, 1, 4162912256, 1, 4162912256, 0, 131072], [3254779904, 1, 4163043328, 1, 4163043328, 0, 131072], [2181038080, 1, 4227858432, 1, 4227858432, 0, 4194304]] is too long Link: https://lore.kernel.org/r/20240704164019.611454-1-Frank.Li@nxp.com Signed-off-by: Frank Li <Frank.Li@nxp.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Reviewed-by: Rob Herring (Arm) <robh@kernel.org>
2024-07-04	dt-bindings: PCI: generic: Add ats-supported property	Jean-Philippe Brucker
	Add a way for firmware to tell the OS that ATS is supported by the PCI root complex. An endpoint with ATS enabled may send Translation Requests and Translated Memory Requests, which look just like Normal Memory Requests with a non-zero AT field. So a root controller that ignores the AT field may simply forward the request to the IOMMU as a Normal Memory Request, which could end badly. In any case, the endpoint will be unusable. The ats-supported property allows the OS to only enable ATS in endpoints if the root controller can handle ATS requests. Only add the property to pcie-host-ecam-generic for the moment. For non-generic root controllers, availability of ATS can be inferred from the compatible string.

2024-05-15	dt-bindings: PCI: host-bridges: Switch from deprecated pci-bus.yaml	Krzysztof Kozlowski
	dtschema package with core schemas deprecated pci-bus.yaml schema in favor of pci-host-bridge.yaml. Update all bindings to use the latter one. The difference between pci-bus.yaml and pci-host-bridge.yaml is only in lack of "reg" property defined by the latter, which should not have any effect here, because all these bindings define the "reg". The change is therefore quite trivial, however it requires dtschema package v2024.02 or newer.

2022-08-01	dt-bindings: PCI: host-generic-pci: Allow IOMMU and MSI properties	Rob Herring
	Allow 'iommu-map', 'iommu-map-mask', and 'msi-parent' properties for generic host. This fixes unevaluated property warnings on Arm Juno, AMD Seattle, and FSL LS1028a. Signed-off-by: Rob Herring <robh@kernel.org> Link: https://lore.kernel.org/r/20220728175137.1172841-1-robh@kernel.org
2020-10-07	dt-bindings: Add missing 'unevaluatedProperties'	Rob Herring
	This doesn't yet do anything in the tools, but make it explicit so we can check either 'unevaluatedProperties' or 'additionalProperties' is present in schemas. 'unevaluatedProperties' is appropriate when including another schema (via '$ref') and all possible properties and/or child nodes are not explicitly listed in the schema with the '$ref'. This is in preparation to add a meta-schema to check for missing 'unevaluatedProperties' or 'additionalProperties'. This has been a constant source of review issues.

2020-01-23	dt-bindings: PCI: Convert generic host binding to DT schema	Rob Herring
	Convert the generic PCI host binding to DT schema. The derivative Juno, PLDA XpressRICH3-AXI, and Designware ECAM bindings all just vary in their compatible strings. The simplest way to convert those to schema is just add them into the common generic PCI host schema. The HiSilicon ECAM and Cavium ThunderX PEM bindings have an additional 'reg' entry, but are otherwise the same binding as well.
