net: ethernet: ravb: Suspend and resume the transmission flow

2026-04-03T23:04:28+00:00

The current driver does not follow the latest datasheet and does not suspend the flow when stopping DMA and resume it when starting. Update the driver to do so.

Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00+00:00

This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds

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

net: ethernet: renesas: rcar_gen4_ptp: Hide private data from users

2026-02-04T03:35:38+00:00

The Gen4 PTP helper module is already used by RTSN and RSWITCH to support PTP clocks and will be used by RAVB too. Hide the Gen4 PTP private data structure to make sure none of the users poke at it. This will be more important for RAVB use-cases as more then one RAVB device will need to cooperate using one PTP clock source.

Instead of accessing the Gen4 PTP specific structure directly in drivers add a helper to read the time. This is done in preparation to completely hide the Gen4 PTP specific structure from users.
