soc: mediatek: mtk-regulator-coupler: Add support for MT8189

2026-09-10T07:40:02+00:00

MT8189 couples its GPU supply (buck_vgpu) with the GPU SRAM supply (ldo_sram_gpu), which is exactly the GPU<->SRAM relationship this coupler already handles for MT8183, MT8186, MT8188 and MT8192. Register the coupler on MT8189 as well so that both supplies stay voltage-balanced. Signed-off-by: Justin Yeh Signed-off-by: AngeloGioacchino Del Regno

soc: mediatek: add missing MODULE_DEVICE_TABLE()

2026-07-30T07:41:54+00:00

The driver has an OF match table wired to .of_match_table, but does not export the table with MODULE_DEVICE_TABLE(). Add the missing MODULE_DEVICE_TABLE(of, ...) entry so module alias information is generated for OF based module autoloading. This is a source-level fix. It does not claim dynamic hardware reproduction; the evidence is the driver-owned match table, its use by the platform driver, and the missing module alias publication.

soc: mediatek: mtk-mmsys: Use MMSYS_ROUTE() in default routing table

2026-07-30T07:41:54+00:00

All of the mtk_mmsys_routes tables for all SoCs were converted to use the MMSYS_ROUTE() macro but the default one used for MT2701, MT2712 and SoCs from that generation was not: convert this one as well. This brings no functional change. Signed-off-by: AngeloGioacchino Del Regno

soc: mediatek: mtk-mmsys: Rework routes to specify component ID

2026-07-30T07:41:54+00:00

In preparation for a refactoring of multimedia related MediaTek drivers, including mmsys, mutex and mediatek-drm, rework all of the MMSYS routes to specify a hardware component instance number (or "SubID") alongside the hardware component type. This also is one step of preparation towards the removal of the catch-all mtk_ddp_comp_id enumeration and towards the migration from a predefined-coupling static hardware component IDSubID mapping (carrying around a very long enumeration and also some multiple big arrays in mediatek-drm) to a more flexible map of Component ID (Type) decoupled from Component SubID (HW Instance) as then, anyway, techniques to handle components are always the same on a type basis.

soc: mediatek: mtk-socinfo Add error handling in devm_kasprintf()

2026-07-09T13:47:35+00:00

Add an error check to the devm_kasprintf() function in mtk_socinfo_create_socinfo_node(), returning -ENOMEM if the function failed.

soc: mediatek: mtk-mmsys: Restore MT8167 routing masks lost during merge

2026-05-11T09:20:48+00:00

The original patch that was sent to the mailing lists included the values for the route masks, but they got lost during merge: add back the full register masks where missing.

soc: mediatek: Use pkt_write function pointer for subsys ID compatibility

2026-05-11T09:15:07+00:00

Switch to pkt_write and reg_write_mask function pointers for register access, enabling compatibility with platforms regardless of subsys ID support. Signed-off-by: Jason-JH Lin Reviewed-by: AngeloGioacchino Del Regno Signed-off-by: AngeloGioacchino Del Regno

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
