IEEE Std 1275-1994 is Inactive-Withdrawn Standard according to https://standards.ieee.org/ieee/1275/1932/. "require at least one non-prefetchable memory and One or both of prefetchable Memory and IO Space may also be provided". But it does not limit maximum ranges number is 3. Inscrease maximum to 8 because freescale ls1028 and iMX95 use more than 3 ranges. Fix below 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 Signed-off-by: Frank Li <Frank.Li@xxxxxxx> --- Documentation/devicetree/bindings/pci/host-generic-pci.yaml | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/Documentation/devicetree/bindings/pci/host-generic-pci.yaml b/Documentation/devicetree/bindings/pci/host-generic-pci.yaml index 3484e0b4b412e..506eed7f6c63d 100644 --- a/Documentation/devicetree/bindings/pci/host-generic-pci.yaml +++ b/Documentation/devicetree/bindings/pci/host-generic-pci.yaml @@ -103,7 +103,7 @@ properties: definition of non-prefetchable memory.
