2023-08-22of: overlay: Extend of_overlay_fdt_apply() to specify the target nodeLizhi Hou
Currently, in an overlay fdt fragment, it needs to specify the exact location in base DT. In another word, when the fdt fragment is generated, the base DT location for the fragment is already known. There is new use case that the base DT location is unknown when fdt fragment is generated. For example, the add-on device provide a fdt overlay with its firmware to describe its downstream devices. Because it is add-on device which can be plugged to different systems, its firmware will not be able to know the overlay location in base DT. Instead, the device driver will load the overlay fdt and apply it to base DT at runtime. In this case, of_overlay_fdt_apply() needs to be extended to specify the target node for device driver to apply overlay fdt. int overlay_fdt_apply(..., struct device_node *base); Signed-off-by: Lizhi Hou <lizhi.hou@amd.com> Link: https://lore.kernel.org/r/1692120000-46900-5-git-send-email-lizhi.hou@amd.com Signed-off-by: Rob Herring <robh@kernel.org>
2023-08-22PCI: Add quirks to generate device tree node for Xilinx Alveo U50Lizhi Hou
The Xilinx Alveo U50 PCI card exposes multiple hardware peripherals on its PCI BAR. The card firmware provides a flattened device tree to describe the hardware peripherals on its BARs. This allows U50 driver to load the flattened device tree and generate the device tree node for hardware peripherals underneath. To generate device tree node for U50 card, add PCI quirks to call of_pci_make_dev_node() for U50.

2023-08-22PCI: Create device tree node for bridgeLizhi Hou
The PCI endpoint device such as Xilinx Alveo PCI card maps the register spaces from multiple hardware peripherals to its PCI BAR. Normally, the PCI core discovers devices and BARs using the PCI enumeration process. There is no infrastructure to discover the hardware peripherals that are present in a PCI device, and which can be accessed through the PCI BARs. Apparently, the device tree framework requires a device tree node for the PCI device. Thus, it can generate the device tree nodes for hardware peripherals underneath. Because PCI is self discoverable bus, there might not be a device tree node created for PCI devices. Furthermore, if the PCI device is hot pluggable, when it is plugged in, the device tree nodes for its parent bridges are required. Add support to generate device tree node for PCI bridges. Add an of_pci_make_dev_node() interface that can be used to create device tree node for PCI devices. Add a PCI_DYNAMIC_OF_NODES config option. When the option is turned on, the kernel will generate device tree nodes for PCI bridges unconditionally. Initially, add the basic properties for the dynamically generated device tree nodes which include #address-cells, #size-cells, device_type, compatible, ranges, reg.

2023-08-21of: dynamic: Move dead property list check into property add/update functionsRob Herring
The changeset code checks for a property in the deadprops list when adding/updating a property, but of_add_property() and of_update_property() do not. As the users of these functions are pretty simple, they have not hit this scenario or else the property lists would get corrupted.

Solve this with a bit of preprocessor magic. Some cases printed the 'cset' which was the changeset entry pointer rather than the whole changeset itself.

2023-08-16dt-bindings: PCI: dwc: rockchip: Fix interrupt-names issueSebastian Reichel
The RK356x (and RK3588) have 5 ganged interrupts. For example the "legacy" interrupt combines "inta/intb/intc/intd" with a register providing the details, which specific interrupt triggered. The interrupts from the second level are part of the Synopsys DW PCIe System Information Interface (SII). Some of them are listed in the Interrupt Signals section, the others are mostly common SII output signals. The grouping and the ganged interrupt controllers are specific to the Rockchip implementation. Currently the binding is not specifying these interrupts resulting in a bunch of errors for all rk356x/rk3588 boards using PCIe. Fix this by specifying the interrupts and add them to the example to prevent regressions. This changes the reference from snps,dw-pcie.yaml to snps,dw-pcie-common.yaml, since the interrupts are vendor specific and should not be listed in the generic file. The only other bit from the generic binding are the reg-names, which are overwritten by this binding.

2023-07-11of: Preserve "of-display" device name for compatibilityRob Herring
Since commit 241d2fb56a18 ("of: Make OF framebuffer device names unique"), as spotted by Frédéric Bonnard, the historical "of-display" device is gone: the updated logic creates "of-display.0" instead, then as many "of-display.N" as required. This means that offb no longer finds the expected device, which prevents the Debian Installer from setting up its interface, at least on ppc64el. Fix this by keeping "of-display" for the first device and "of-display.N" for subsequent devices.

2023-07-10of: make OF_EARLY_FLATTREE depend on HAS_IOMEMBaoquan He
On s390 systems (aka mainframes), it has classic channel devices for networking and permanent storage that are currently even more common than PCI devices. Hence it could have a fully functional s390 kernel with CONFIG_PCI=n, then the relevant iomem mapping functions [including ioremap(), devm_ioremap(), etc.] are not available. In LKP error report at below on s390: ------ ld: kernel/dma/coherent.o: in function `dma_init_coherent_memory': coherent.c:(.text+0x102): undefined reference to `memremap' ld: coherent.c:(.text+0x226): undefined reference to `memunmap' ld: kernel/dma/coherent.o: in function `dma_declare_coherent_memory': coherent.c:(.text+0x8b8): undefined reference to `memunmap' ld: kernel/dma/coherent.o: in function `dma_release_coherent_memory': coherent.c:(.text+0x9aa): undefined reference to `memunmap' ------ In the config file, several Kconfig options are: ------ '# CONFIG_PCI is not set' CONFIG_OF_EARLY_FLATTREE=y CONFIG_DMA_DECLARE_COHERENT=y ------ So, enabling OF_EARLY_FLATTREE will select DMA_DECLARE_COHERENT and cause above building errors even though they are not needed because CONFIG_PCI is disabled. Here let OF_EARLY_FLATTREE depend on HAS_IOMEM so that it won't be built to cause compiling error if PCI is unset.

We just sorted the entries and fields last release, so just out of a perverse sense of curiosity, I decided to see if we can keep things ordered for even just one release. The answer is "No. No we cannot". I suggest that all kernel developers will need weekly training sessions, involving a lot of Big Bird and Sesame Street. And at the yearly maintainer summit, we will all sing the alphabet song together. I doubt I will keep doing this. At some point "perverse sense of curiosity" turns into just a cold dark place filled with sadness and despair.
