of: Move of_platform_register_reconfig_notifier() into DT core

2023-08-04T17:36:33+00:00

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

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

2023-04-10T23:32:31+00:00

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()

2022-07-08T12:53:50+00:00

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

2017-09-19T17:20:44+00:00

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

2017-05-22T16:01:46+00:00

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

2017-02-27T16:20:13+00:00

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.

of/platform: add function to populate default bus

2015-08-25T16:29:55+00:00

When a default bus like the simple-bus should be used someone had to call of_platform_populate() with the default match table. This match table was not exported, so it is impossible for code build as a module to use this. Instead of exporting of_default_bus_match_table, add a new function which uses this default match table and populates the bus. Signed-off-by: Hauke Mehrtens Signed-off-by: Rob Herring

of/platform: Fix sparc:allmodconfig build

sparc:allmodconfig fails to build with: drivers/built-in.o: In function `platform_bus_init': (.init.text+0x3684): undefined reference to `of_platform_register_reconfig_notifier' of_platform_register_reconfig_notifier is only declared if both OF_ADDRESS and OF_DYNAMIC are configured. Yet, the include file only declares a dummy function if OF_DYNAMIC is not configured. The sparc architecture does not configure OF_ADDRESS, but does configure OF_DYNAMIC, causing above error.
