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.

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

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

soc: mediatek: mtk-cmdq: Add mminfra_offset adjustment for DRAM addresses

2026-01-19T11:57:46+00:00

Since GCE has been moved to MMINFRA in MT8196, all transactions from MMINFRA to DRAM will have their addresses adjusted by subtracting a mminfra_offset. Therefore, the CMDQ helper driver needs to get the mminfra_offset value of the SoC from cmdq_mbox_priv of cmdq_pkt and then add it to the DRAM address when generating instructions to ensure GCE accesses the correct DRAM address. CMDQ users can then call CMDQ helper APIs as usual.

soc: mediatek: mtk-cmdq: Extend cmdq_pkt_write API for SoCs without subsys ID

2026-01-19T11:57:45+00:00

This patch extends the cmdq_pkt_write API to support SoCs that do not have subsys ID mapping by introducing new register write APIs: - cmdq_pkt_write_pa() and cmdq_pkt_write_subsys() replace cmdq_pkt_write() - cmdq_pkt_write_mask_pa() and cmdq_pkt_write_mask_subsys() replace cmdq_pkt_write_mask() To ensure consistent function pointer interfaces, both cmdq_pkt_write_pa() and cmdq_pkt_write_subsys() provide subsys and pa_base parameters. This unifies how register writes are invoked, regardless of whether subsys ID is supported by the device. All GCEs support writing registers by PA (with mask) without subsys, but this requires extra GCE instructions to convert the PA into a GCE readable format, reducing performance compared to using subsys directly. Therefore, subsys is preferred for register writes when available. API documentation and function pointer declarations in cmdq_client_reg have been updated. The original write APIs will be removed after all CMDQ users transition to the new interfaces.
