263291fa - sparc: Explicitly include correct DT includes

Tue, 18 Jul 2023 20:45:20 +0000

sparc: Explicitly include correct DT includesThe DT of_device.h and of_platform.h date back to the separateof_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. They also include platform_device.hand of.h. As a result, there's a pretty much random mix of those includefiles used throughout the tree. In order to detangle these headers andreplace the implicit includes with struct declarations, users need toexplicitly include the correct includes.Acked-by: Sam Ravnborg Link: https://lore.kernel.org/all/20230718143211.1066810-1-robh@kernel.org/Signed-off-by: Rob Herring List of files: /linux-6.15/arch/sparc/kernel/of_device_common.c

6a71ca74 - sparc: Use of_property_present() for testing DT property presence

Fri, 10 Mar 2023 14:46:59 +0000

sparc: Use of_property_present() for testing DT property presenceIt is preferred to use typed property access functions (i.e.of_property_read_ functions) rather than low-levelof_get_property/of_find_property functions for reading properties. Aspart of this, convert of_get_property/of_find_property calls to therecently added of_property_present() helper when we just want to testfor presence of a property and nothing more.Link: https://lore.kernel.org/r/20230310144659.1541247-1-robh@kernel.orgSigned-off-by: Rob Herring List of files: /linux-6.15/arch/sparc/kernel/of_device_common.c

eca39301 - of: Merge of_platform_bus_type with platform_bus_type

Tue, 08 Jun 2010 13:48:21 +0000

of: Merge of_platform_bus_type with platform_bus_typeof_platform_bus was being used in the same manner as the platform_bus.The only difference being that of_platform_bus devices are generatedfrom data in the device tree, and platform_bus devices are usuallystatically allocated in platform code. Having them separate causesthe problem of device drivers having to be registered twice if itwas possible for the same device to appear on either bus.This patch removes of_platform_bus_type and registers all of_platformbus devices and drivers on the platform bus instead. A previous patchmade the of_device structure an alias for the platform_device structure,and a shim is used to adapt of_platform_drivers to the platform bus.After all of of_platform_bus drivers are converted to be normal platformdrivers, the shim code can be removed.Signed-off-by: Grant Likely Acked-by: David S.

1636f8ac - sparc/of: Move of_device fields into struct pdev_archdata

Fri, 18 Jun 2010 17:09:58 +0000

sparc/of: Move of_device fields into struct pdev_archdataThis patch moves SPARC architecture specific data members out ofstruct of_device and into the pdev_archdata structure. The reasonfor this change is to unify the struct of_device definition amongstall the architectures. It also remvoes the .sysdata, .slot, .portidand .clock_freq properties because they aren't actually used byanything.A subsequent patch will replace struct of_device entirely with structplatform_device and the of_platform support code will share commonroutines with the platform bus (but the bus instances themselves canremain separate).This patch also adds 'struct resources *resource' and num_resourcesto match the fields defined in struct platform_device. After thischange, 'struct platform_device' can be used as a drop-in replacementfor 'struct of_platform'.This change is in preparation for merging the of_platform_bus_typewith the platform_bus_type.Signed-off-by: Grant Likely Acked-by: David S.

5a0e3ad6 - include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h

Wed, 24 Mar 2010 08:04:11 +0000

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.hpercpu.h is included by sched.h and module.h and thus ends up beingincluded when building most .c files. percpu.h includes slab.h whichin turn includes gfp.h making everything defined by the two filesuniversally available and complicating inclusion dependencies.percpu.h -> slab.h dependency is about to be removed. Prepare forthis change by updating users of gfp and slab facilities include thoseheaders directly instead of assuming availability. As this conversionneeds to touch large number of source files, the following script isused as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.pyThe script does the followings.* Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h.* When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order.* If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file.The conversion was done in the following steps.1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files.2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files.3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind.4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually.5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary.6. percpu.h was updated not to include slab.h.7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point.Given the fact that I had only a couple of failures from tests on step6, I'm fairly confident about the coverage of this conversion patch.If there is a breakage, it's likely to be something in one of the archheaders which should be easily discoverable easily on most builds ofthe specific arch.Signed-off-by: Tejun Heo Guess-its-ok-by: Christoph Lameter Cc: Ingo Molnar Cc: Lee Schermerhorn List of files: /linux-6.15/arch/sparc/kernel/of_device_common.c
