"ipk" is still a bit unspecific, I was hoping to see a specific chip and/or version of the PCIe part. Something like compatible = "snps,ipk2040-pcie", "snps,ipk-pcie", "snps,dw-pcie-1.23", "snps,dw-pcie"; which would indicate that there is a chip called "ipk2040" in a family called "ipk", and this includes the designware pcie implementation in version 1.23. > > - update the devicetree documentation referring that the ranges also include the > > config space > > Another one for Arnd. This one is wrong, the ranges should *not* include the config space, and if they currently do, you must change the driver. The generic dw-pcie driver still accepts the config space in the ranges for backwards compatibility with some of the earlier front-ends that mistakenly did this, but new driver should not do the same, and we should probably add some code in the common driver to prevent it for front-ends other than the ones we have to keep compatibility with.
