base: soc: rename and export soc_device_get_machine()

2026-03-12T15:18:49Z

Some SoC drivers reimplement the functionality of soc_device_get_machine(). Make this function accessible through the sys_soc.h header and rename it to a more descriptive name.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

driver core: mark remaining local bus_type variables as const

2023-12-21T12:56:30Z

Now that the driver core can properly handle constant struct bus_type, change the local driver core bus_type variables to be a constant structure as well, placing them into read-only memory which can not be modified at runtime.

base: soc: Remove usage of the deprecated ida_simple_xx() API

2023-12-07T02:22:23Z

ida_alloc() and ida_free() should be preferred to the deprecated ida_simple_get() and ida_simple_remove(). This is less verbose.

base: soc: populate machine name in soc_device_register if empty

2023-03-29T10:21:23Z

Several SoC drivers use the same of-based mechanism to populate the machine name. Therefore move this to the core and try to populate the machine name in soc_device_register if it's not set yet.

driver core: soc: remove layering violation for the soc_bus

2023-01-31T08:09:53Z

The soc_bus code pokes around in the internal bus structures assuming that it "knows" if a field is not set that it has not been registered yet. That isn't a safe assumption, so just remove the layering violation entirely and keep track if the bus has been registered or not ourselves. Reviewed-by: Rafael J.

base: soc: Make soc_device_match() simpler and easier to read

2022-03-18T13:28:07Z

The function soc_device_match() is difficult to read for various reasons: - There are two loop conditions using different styles: "while (...)" (which is BTW always true) vs. "if ... break", - The are two return condition using different logic: "if ... return foo" vs. "if ... else return bar". Make the code easier to read by: 1. Removing the always-true "!ret" loop condition, and dropping the now unneeded pre-initialization of "ret", 2. Converting "if ... break" to a proper "while (...)" loop condition, 3. Inverting the logic of the second return condition.

soc: fix comment for freeing soc_dev_attr

2020-12-09T18:46:31Z

The soc_dev_attr is stored soc_dev->attr during soc_device_register() so it could be used till the cleanup call: soc_device_unregister(). Therefore this memory should not be freed prior, but after unregistering soc device.
