net: ipa: add IPA v5.2 configuration data

net: ipa: Fix programming of QTIME_TIMESTAMP_CFG

2026-04-12T20:49:32+00:00

The 'val' variable gets overwritten multiple times, discarding previous values. Looking at the git log shows these should be combined with |= instead.

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: ipa: Remove redundant pm_runtime_mark_last_busy() calls

2025-10-30T01:55:56+00:00

pm_runtime_put_autosuspend(), pm_runtime_put_sync_autosuspend(), pm_runtime_autosuspend() and pm_request_autosuspend() now include a call to pm_runtime_mark_last_busy(). Remove the now-reduntant explicit call to pm_runtime_mark_last_busy().

net: Use of_reserved_mem_region_to_resource{_byname}() for "memory-region"

2025-07-08T15:29:46+00:00

Use the newly added of_reserved_mem_region_to_resource{_byname}() functions to handle "memory-region" properties. The error handling is a bit different for mtk_wed_mcu_load_firmware(). A failed match of the "memory-region-names" would skip the entry, but then other errors in the lookup and retrieval of the address would not skip the entry. However, that distinction is not really important. Either the region is available and usable or it is not. So now, errors from of_reserved_mem_region_to_resource() are ignored so the region is simply skipped.

net: Switch back to struct platform_driver::remove()

2024-10-04T23:39:57+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/net after the previous conversion commits apart from the wireless drivers to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

net: ipa: kill ipa_version_supported()

2024-04-23T11:08:08+00:00

The only place ipa_version_supported() is called is in the probe function. The version comes from the match data. Rather than checking the version validity separately, just consider anything that has match data to be supported. Signed-off-by: Alex Elder Signed-off-by: Paolo Abeni

net: ipa: fix two minor ipa_cmd problems

2024-04-23T11:08:08+00:00

In "ipa_cmd.h", ipa_cmd_data_valid() is declared, but that function does not exist. So delete that declaration. Also, for some reason ipa_cmd_init() never gets called. It isn't really critical--it just validates that some memory offsets and a size can be represented in some register fields, and they won't fail with current data. Regardless, call the function in ipa_probe(). Signed-off-by: Alex Elder Signed-off-by: Paolo Abeni
