2024-03-01of: property: fw_devlink: Fix stupid bug in remote-endpoint parsingSaravana Kannan
Introduced a stupid bug in commit 782bfd03c3ae ("of: property: Improve finding the supplier of a remote-endpoint property") due to a last minute incorrect edit of "index !=0" into "!index". This patch fixes it to be "index > 0" to match the comment right next to it.

2024-02-09of: property: Add in-ports/out-ports support to of_graph_get_port_parent()Saravana Kannan
Similar to the existing "ports" node name, coresight device tree bindings have added "in-ports" and "out-ports" as standard node names for a collection of ports. Add support for these name to of_graph_get_port_parent() so that remote-endpoint parsing can find the correct parent node for these coresight ports too.

2024-02-09of: property: Improve finding the supplier of a remote-endpoint propertySaravana Kannan
After commit 4a032827daa8 ("of: property: Simplify of_link_to_phandle()"), remote-endpoint properties created a fwnode link from the consumer device to the supplier endpoint. This is a tiny bit inefficient (not buggy) when trying to create device links or detecting cycles. So, improve this the same way we improved finding the consumer of a remote-endpoint property.

2024-01-09of: Fix double free in of_parse_phandle_with_args_mapChristian A. Ehrhardt
In of_parse_phandle_with_args_map() the inner loop that iterates through the map entries calls of_node_put(new) to free the reference acquired by the previous iteration of the inner loop. This assumes that the value of "new" is NULL on the first iteration of the inner loop. Make sure that this is true in all iterations of the outer loop by setting "new" to NULL after its value is assigned to "cur". Extend the unittest to detect the double free and add an additional test case that actually triggers this path.

2023-12-07of/platform: Disable sysfb if a simple-framebuffer node is foundJavier Martinez Canillas
Some DT platforms use EFI to boot and in this case the EFI Boot Services may register a EFI_GRAPHICS_OUTPUT_PROTOCOL handle, that will later be queried by the Linux EFI stub to fill the global struct screen_info data. The data is used by the Generic System Framebuffers (sysfb) framework to add a platform device with platform data about the system framebuffer. But if there is a "simple-framebuffer" node in the DT, the OF core will also do the same and add another device for the system framebuffer. This could lead for example, to two platform devices ("simple-framebuffer" and "efi-framebuffer") to be added and matched with their corresponding drivers. So both efifb and simpledrm will be probed, leading to following: [ 0.055752] efifb: framebuffer at 0xbd58dc000, using 16000k, total 16000k [ 0.055755] efifb: mode is 2560x1600x32, linelength=10240, pages=1 [ 0.055758] efifb: scrolling: redraw [ 0.055759] efifb: Truecolor: size=2:10:10:10, shift=30:20:10:0 ... [ 3.295896] simple-framebuffer bd58dc000.framebuffer: [drm] *ERROR* could not acquire memory range [??? 0xffff79f30a29ee40-0x2a5000001a7 flags 0x0]: -16 [ 3.298018] simple-framebuffer: probe of bd58dc000.framebuffer failed with error -16 To prevent the issue, make the OF core to disable sysfb if there is a node with a "simple-framebuffer" compatible. That way only this device will be registered and sysfb would not attempt to register another one using the screen_info data even if this has been filled. This seems the correct thing to do in this case because: a) On a DT platform, the DTB is the single source of truth since is what describes the hardware topology. Even if EFI Boot Services are used to boot the machine. b) The of_platform_default_populate_init() function is called in the arch_initcall_sync() initcall level while the sysfb_init() function is called later in the subsys_initcall() initcall level.

2023-10-27of: address: Consolidate bus .map() functionsRob Herring
The bus .map() functions vary only by checking the flag cells values and skipping over any flag cells to read the addresses. Otherwise they all do the same reading 'ranges' address and size and returning the address's offset if it is within the 'ranges' entry. Refactor all the .map() functions to pass in the flag cell size so that each bus can check the bus specific flags and then call a common function to do everything else.

2023-10-26of: address: Fix address translation when address-size is greater than 2Herve Codina
With the recent addition of of_pci_prop_ranges() in commit 407d1a51921e ("PCI: Create device tree node for bridge"), the ranges property can have a 3 cells child address, a 3 cells parent address and a 2 cells child size. A range item property for a PCI device is filled as follow: <BAR_nbr> 0 0 <phys.hi> <phys.mid> <phys.low> <BAR_sizeh> <BAR_sizel> <-- Child --> <-- Parent (PCI definition) --> <- BAR size (64bit) --> This allow to translate BAR addresses from the DT. For instance: pci@0,0 { #address-cells = <0x03>; #size-cells = <0x02>; device_type = "pci"; compatible = "pci11ab,100", "pciclass,060400", "pciclass,0604"; ranges = <0x82000000 0x00 0xe8000000 0x82000000 0x00 0xe8000000 0x00 0x4400000>; ... dev@0,0 { #address-cells = <0x03>; #size-cells = <0x02>; compatible = "pci1055,9660", "pciclass,020000", "pciclass,0200"; /* Translations for BAR0 to BAR5 */ ranges = <0x00 0x00 0x00 0x82010000 0x00 0xe8000000 0x00 0x2000000 0x01 0x00 0x00 0x82010000 0x00 0xea000000 0x00 0x1000000 0x02 0x00 0x00 0x82010000 0x00 0xeb000000 0x00 0x800000 0x03 0x00 0x00 0x82010000 0x00 0xeb800000 0x00 0x800000 0x04 0x00 0x00 0x82010000 0x00 0xec000000 0x00 0x20000 0x05 0x00 0x00 0x82010000 0x00 0xec020000 0x00 0x2000>; ... pci-ep-bus@0 { #address-cells = <0x01>; #size-cells = <0x01>; compatible = "simple-bus"; /* Translate 0xe2000000 to BAR0 and 0xe0000000 to BAR1 */ ranges = <0xe2000000 0x00 0x00 0x00 0x2000000 0xe0000000 0x01 0x00 0x00 0x1000000>; ... }; }; }; During the translation process, the "default-flags" map() function is used to select the matching item in the ranges table and determine the address offset from this matching item. This map() function simply calls of_read_number() and when address-size is greater than 2, the map() function skips the extra high address part (ie part over 64bit). This lead to a wrong matching item and a wrong offset computation. Also during the translation itself, the extra high part related to the parent address is not present in the translated address. Fix the "default-flags" map() and translate() in order to take into account the child extra high address part in map() and the parent extra high address part in translate() and so having a correct address translation for ranges patterns such as the one given in the example above.

2023-10-17amba: bus: balance firmware node reference countingAndy Shevchenko
Currently the ACPI code doesn't bump the reference count of the firmware node, while OF counter part does. Not that it's a problem right now, since ACPI doesn't really use the reference counting for firmware nodes, it still makes sense to make code robust against any changes done there. For this, - switch ACPI case to use device_set_node() to be unified with OF - move reference counting to amba_device_add() - switch to use firmware nodes instead of OF ones In the result we will have reference counting done in the same module for all callers independently on the nature of firmware node behind.

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.

of_unittest_apply_overlay_check() and the first part of of_unittest_apply_revert_overlay_check() are identical. Reduce code duplication by replacing them by two wrappers around a common helper.

2023-08-23of: unittest: Improve messages and comments in apply/revert checksGeert Uytterhoeven
Miscellaneous improvements for the apply and apply/revert checks, making them more similar: - Fix inverted comment for before state check, - Add more comments to improve symmetry, - Fix grammar s/must be to set to/must be in/, - Avoid saying "create" in messages, as the actual operation depends on the value of the before/after parameters.

When updating the expected error messages for the overlay_bad_add_dup_prop test, indentation of the EXPECT_END() statements was accidentally changed.

2023-08-23of: unittest: Fix overlay type in apply/revert checkGeert Uytterhoeven
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.
