Hello I have an X86 platform with device tree support. It has multiple pci slots with a custom board that is described with a device tree. When the pci device is probed, the driver fetches a device tree from the firmware infrastructure, patches the range property based on the bar address and adds the device to the main device tree. This works perfectly fine with only one card, but when the second card is connected: Here be dragons :) The main issue is that of_find_node_by_phandle always resolves to the first connected card. I fixed this by creating a new function. of_find_node_by_phandle_family() that chooses the closest phandle on the tree, not just the first one. By reading the "Dynamic Symbols support and fixup support" here: http://events.linuxfoundation.org/sites/events/files/slides/dynamic-dt-elce14.pdf and here https://lwn.net/Articles/616859/ It seemed that the patch would fix my issue and it would be already merged, but I cannot find the patch here https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git or here https://git.kernel.org/cgit/linux/kernel/git/jdl/dtc.git So I am wondering some stuff: Would a patch adding my of_find_node_by_phandle_family() would be accepted.? Will Dynamic symbols fix my issue? What is the status of Dynamic symbol support?
