of: device: Export of_device_make_bus_id()

2023-12-15T12:30:07Z

This helper is really handy to create unique device names based on their device tree path, we may need it outside of the OF core (in the NVMEM subsystem) so let's export it. As this helper has nothing patform specific, let's move it to of/device.c instead of of/platform.c so we can add its prototype to of_device.h.

iommmu/of: Do not return struct iommu_ops from of_iommu_configure()

2023-12-12T09:18:47Z

Nothing needs this pointer. Return a normal error code with the usual IOMMU semantic that ENODEV means 'there is no IOMMU driver'.

iommu: Remove struct iommu_ops *iommu from arch_setup_dma_ops()

2023-12-12T09:18:45Z

This is not being used to pass ops, it is just a way to tell if an iommu driver was probed. These days this can be detected directly via device_iommu_mapped(). Call device_iommu_mapped() in the two places that need to check it and remove the iommu parameter everywhere.

Pull devicetree updates from Rob Herring: "DT core: - Add support for generating DT nodes for PCI devices.

of: module: Export of_device_uevent()

2023-07-21T07:07:53Z

The content of of_device_uevent() is currently hardcoded in a driver that can be compiled as a module. Nothing prevents of_device_uevent() to be exported to modules, most of the other helpers in of/device.c actually are. The reason why this helper was not exported is because it has been so far only useful in drivers/base, which is built-in anyway. With the idea of getting rid of the hardcoded implementation of of_device_uevent() in other places in the kernel, let's export it to GPL modules (very much like its cousins in the same file).

of: Move the request module helper logic to module.c

2023-04-05T17:41:10Z

Depending on device.c for pure OF handling is considered backwards. Let's extract the content of of_device_request_module() to have the real logic under module.c. The next step will be to convert users of of_device_request_module() to use the new helper.

of: Move of_modalias() to module.c

2023-04-05T17:41:10Z

Create a specific .c file for OF related module handling. Move of_modalias() inside as a first step. The helper is exposed through of.h even though it is only used by core files because the users from device.c will soon be split into an OF-only helper in module.c as well as a device-oriented inline helper in of_device.h. Putting this helper in of_private.h would require to include of_private.h from of_device.h, which is not acceptable.
