clk: versatile: Make sure clk_init_data is fully initialized

2026-08-31T15:29:39+00:00

The clk_init_data structure contains several mutually-exclusive members for different methods to specify the possible parents of a clock, prompting drivers to initialize only the members they need. However, not initializing all members may cause subtle issues, which are only exposed when CONFIG_INIT_STACK_ALL_PATTERN or CONFIG_INIT_STACK_NONE is enabled. Make sure all members are fully initialized, to avoid such bugs, and to prevent future breakage when converting drivers to a different method for specifying the parents.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

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

clk: Use of_property_present()

2024-08-02T23:53:38+00:00

Use of_property_present() to test for property presence rather than of_(find|get)_property(). This is part of a larger effort to remove callers of of_find_property() and similar functions. of_(find|get)_property() leak the DT struct property and data pointers which is a problem for dynamically allocated nodes which may be freed.

clk: versatile: sp810: Add a determine_rate hook

2023-06-09T01:39:31+00:00

The Versatile sp810 "timerclken" clock implements a mux with a set_parent hook, but doesn't provide a determine_rate implementation. This is a bit odd, since set_parent() is there to, as its name implies, change the parent of a clock. However, the most likely candidates to trigger that parent change are either the assigned-clock-parents device tree property or a call to clk_set_rate(), with determine_rate() figuring out which parent is the best suited for a given rate. This mismatch is probably due to the fact that the driver introduction predates the determine_rate introduction, and it was never revised since then. The default, implicit, behaviour that has been in use so far has thus been to simply keep using the current parent in all cases. This is also the behaviour of the new clk_hw_determine_rate_no_reparent() helper, so we can simply use it to make our expectation explicit.
