Here's the set of 2 patches against Simon Horman's 'renesas.git' repo's 'renesas-devel-v3.16-rc1-20140618' tag. Here we add PCI USB device tree support for the R8A7790-based Lager board. As the 'pci-rcar-gen2' driver device tree support has been merged for 3.16, this patchset can now be merged too...

It also needs a device_type property. I realize that the driver doesn't currently use them, but you should adhere to the binding anyway, so we can fix the driver at some point.

Yes, I realized that too late as well, sorry about it. For some reason I only looked at the interrupt-map being done right and forgot to check the ranges. We definitely need to move the code handling the ranges into a common location to avoid this mistake in the future. Arnd ^ permalink raw reply [flat|nested] 10+ messages in thread

It probably made more sense on real Open Firmware than it does on FDT, but we're trying to follow the bindings anyway. I believe the "device_type=pci" originally indicated a device that has a readable config space (through the OF client interface), which is true for both the host and the devices. > >>> I realize that the driver doesn't currently use them, but you should > >>> adhere to the binding anyway, so we can fix the driver at some point. > > >> Sigh, agreed about the need to fix the driver.

We have some common helpers for "ranges" parsing already, but we should improve them so a driver has to do much less in the future. For "dma-ranges", we still to write need most of the code. For platform devices, we can now calculate the offset for the simple (no IOMMU) case, but we still need to calculate the dma mask correctly (that part should be simple, maybe you can help there as you have an immediate need), and we need to handle the IOMMU and swiotlb cases better. For PCI devices, we need to do all the same things we do for platform devices, and we can probably share most of the code. Arnd ^ permalink raw reply [flat|nested] 10+ messages in thread

It is confusingly named, but it is required on the host bridge OF node. The spec says ' .. corresponding to a device that implements a PCI bus', which includes the host bridge. The key element is that it must be present on the node that introduces the PCI 3 dword address encoding scheme, and then on all nodes below it that use the 3 dword scheme. Otherwise Linux common OF PCI code does not work properly. Jason ^ permalink raw reply [flat|nested] 10+ messages in thread
