of: Stop circularly including of_device.h and of_platform.h

2024-01-19T14:17:28Z

The DT of_device.h and of_platform.h headers date back to the separate of_platform_bus_type before it was merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. The headers also include platform_device.h and of.h. The result was lots of drivers relied on these implicit includes. Now the entire tree has been fixed over the last couple of cycles to explicitly include the necessary headers instead of relying on of_device.h and/or of_platform.h implicit includes, so the implicit and circular includes can finally be removed.

of: Move of_platform_register_reconfig_notifier() into DT core

2023-08-04T17:36:33Z

There's no reason the generic platform bus code needs to call of_platform_register_reconfig_notifier(). The notifier can be setup before the platform bus is. Let's move it into of_core_init() which is called just before platform_bus_init() instead to keep more of the DT bits in the DT code.

of: Drop unnecessary includes in headers

2023-04-13T22:46:34Z

Drop unnecessary includes in DT headers. Some simply aren't needed and some can be replaced with forward declarations. Link: https://lore.kernel.org/r/20230329-dt-cpu-header-cleanups-v1-5-581e2605fe47@kernel.org Signed-off-by: Rob Herring

of: Move of_device_(add|register|unregister) to of_platform.h

2023-04-10T23:32:31Z

As of_device_(add|register|unregister) functions work on struct platform_device, they should be declared in of_platform.h instead. This move is transparent for now as both headers include each other.

of/platform: Add stubs for of_platform_device_create/destroy()

2022-07-08T12:53:50Z

Code for platform_device_create() and of_platform_device_destroy() is only generated if CONFIG_OF_ADDRESS=y. Add stubs to avoid unresolved symbols when CONFIG_OF_ADDRESS is not set.

of: provide inline helper for of_find_device_by_node

2017-09-19T17:20:44Z

The ipmmu-vmsa driver fails in compile-testing on non-OF platforms: drivers/iommu/ipmmu-vmsa.o: In function `ipmmu_of_xlate': ipmmu-vmsa.c:(.text+0x740): undefined reference to `of_find_device_by_node' It would be reasonable to assume that this interface works but returns failure on non-OF builds, like it does on machines that have been booted in another way, so this adds another inline function helper.

of/platform: Make of_platform_device_destroy globally visible

2017-05-22T16:01:46Z

of_platform_device_destroy is the counterpart to of_platform_device_create which is a non-static function. After creating a platform device it might be neccessary to destroy it to deal with -EPROBE_DEFER where a repeated of_platform_device_create call would fail otherwise. Therefore also make of_platform_device_destroy globally visible. Signed-off-by: Jan Glauber Acked-by: Rob Herring Signed-off-by: Ulf Hansson

of: add devm_ functions for populate and depopulate

2017-02-27T16:20:13Z

Lots of calls to of_platform_populate() are not unbalanced by a call to of_platform_depopulate(). This create issues while drivers are bind/unbind. In way to solve those issues is to add devm_of_platform_populate() which will call of_platform_depopulate() when the device is unbound from the bus.
