dm: core: free old name in device_set_name to prevent leak

2026-07-16T18:03:05Z

If device_set_name is called on a device that already has DM_FLAG_NAME_ALLOCED set, the old dynamically-allocated name is leaked. Free it before assigning the new name. See: drivers/net/mdio_gpio.c:mdio_gpio_bind(). There is device_set_name() here, however dm_mdio_post_bind() will also call device_set_name() if "device-name" exists.

dm: core: Correct calloc arguments

2026-07-16T18:03:05Z

Every other calloc in drivers/core uses calloc(count, size) with count first. Fix the two reversed calloc(sizeof, 1) calls for consistency. Signed-off-by: Peng Fan Reviewed-by: Raphaël Gallais-Pou Reviewed-by: Simon Glass

dm: core: fix wrong strlen check in of_add_subnode

2026-07-16T18:03:05Z

The duplicate-name check uses strlen on the search name instead of the child name, so a child named "trevor" would falsely match a search for "trev". Fix by checking strlen of child->name. Signed-off-by: Peng Fan Reviewed-by: Raphaël Gallais-Pou Reviewed-by: Simon Glass

dm: core: free fdt when fdt_create_empty_tree failure

2026-07-16T18:03:05Z

If fdt_create_empty_tree fails, the malloc-ed fdt buffer is never freed. Add free before the error return. Signed-off-by: Peng Fan Reviewed-by: Raphaël Gallais-Pou Reviewed-by: Simon Glass

treewide: Staticize and constify acpi ops

2026-06-29T21:29:44Z

Set the acpi_ops structure as static const where applicable. The The structure is not accessible from outside of drivers and is not going to be modified at runtime. The structure may be unused in a couple of drivers depending on their configuration, mark those sites with __maybe_unused . Signed-off-by: Marek Vasut Reviewed-by: Simon Glass

dm: core: Remove dependency on CLK

CLK is an optional dependency of simple-pm-bus. Remove the dependency. Fixes: 447bd8f1e5cf ("simple-pm-bus: Make clocks optional") Signed-off-by: Markus Schneider-Pargmann (TI)

dm: core: Split SIMPLE_PM_BUS into phases

2026-06-12T19:01:24Z

Similar to SIMPLE_BUS, create a SPL_SIMPLE_PM_BUS additional to the SIMPLE_PM_BUS. Most boards will not need SIMPLE_PM_BUS in SPL. This is currently needed to reduce the SPL size for beagle bone black with OF_UPSTREAM enabled. Reviewed-by: Simon Glass Reviewed-by: Kory Maincent Signed-off-by: Markus Schneider-Pargmann (TI)

dm: core: use DT region size when mapping device addresses

2026-06-11T16:02:32Z

Update dev_read_addr_*_ptr() and dev_remap_addr_*() helpers to use dev_read_addr_size_*() and pass the DT-provided region size to map_sysmem() / map_physmem() instead of 0. Ensure mappings are consistent with the size defined in the device tree and avoids implicit or unbounded mappings. When the DT does not provide a size, the behavior remains unchanged since size is initialized to 0. Signed-off-by: Peng Fan

Merge patch series "add memdup_nul(), use it and memdup() in a few places"

2026-05-12T21:41:52Z

Rasmus Villemoes says: There are quite a few places where we allocate X+1 bytes, initialize the first X bytes via memcpy() and then set the last byte to 0. The kernel has a helper for that, kmemdup_nul(). Introduce a similar one, and start making use of it in a few places. Also the existing memdup() helper can be put to more use. There are lots more places one could modify. But for code shared with host tools, one would need to do some refactoring, putting memdup() and memdup_nul() in their own str-util.c TU which could then also be included in the tools build.

drivers/core: use memdup() instead of malloc()+memcpy()

2026-05-12T21:38:00Z

Use memdup() instead of open-coding it. In the dm_setup_inst() case, there was never any reason to use calloc(), as the whole allocation is definitely initialized via the immediately following memcpy(). Reviewed-by: Simon Glass Signed-off-by: Rasmus Villemoes
