The Saef SF-TC154B is a 1.54 inch 240x240 square panel with a MIPI DBI compatible interface. The panel is used on the Anbernic RG-Nano handheld gaming device. The initialization of the panel requires a firmware binary which can be made with the mipi-dbi-cmd[1] tool. The command sequence needed can be found in both source[2] and binary form[3].

of_unittest_pci_node test depends on both CONFIG_PCI_DYNAMIC_OF_NODES and CONFIG_OF_OVERLAY. Move the test into the existing CONFIG_OF_OVERLAY ifdef and rework the CONFIG_PCI_DYNAMIC_OF_NODES dependency to use IS_ENABLED() instead. This reduces the combinations to build. Reported-by:

Overlay syntactic sugar for generating target-path fragments is supported by the version of dtc supplied with the kernel since commit 50aafd60 ("scripts/dtc: Update to upstream version v1.4.6-21-g84e414b0b5bc").

When of_overlay_fdt_apply() fails, the changeset may be partially applied, and the caller is still expected to call of_overlay_remove() to clean up this partial state. However, overlay_17 is the only test that takes care of cleaning up after an (expected) failure. Instead of adding cleanup code to each individual test, extend overlay_info with the optional expected return value of of_overlay_remove(), and handle cleanup in the overlay_data_apply() helper. While at it, simplify the end marker in the overlay_info table. Update the expected error output for errors during the newly cleanup. Signed-off-by:

The removal check in of_unittest_apply_revert_overlay_check() always uses the platform device overlay type, while it should use the actual overlay type, as passed as a parameter to the function. This has no impact on any current test, as all tests calling of_unittest_apply_revert_overlay_check() use the platform device overlay type.

When of_overlay_fdt_apply() fails, the changeset may be partially applied, and the caller is still expected to call of_overlay_remove() to clean up this partial state. However, of_overlay_apply() calls of_resolve_phandles() before init_overlay_changeset(). Hence if the overlay fails to apply due to an unresolved symbol, the overlay_changeset.cset.entries list is still uninitialized, and cleanup will crash with a NULL-pointer dereference in overlay_removal_is_ok(). Fix this by moving the call to of_changeset_init() from init_overlay_changeset() to of_overlay_fdt_apply(), where all other early initialization is done.

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: -

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. Acked-by:

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. Acked-by:

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. With this there are 3 cases of removing a property from either deadprops or properties lists, so add a helper to find and remove a matching property. Reviewed-by:
