From: Congcong Yao via B4 Relay

Date: Mon Aug 31 2026 - 02:55:02 EST


This patchset adds MT8189 SMI support.

The series updates the MediaTek SMI bindings for MT8189 and adds the
corresponding SMI common and LARB support in the mtk-smi driver.

Based on commit e30626823a40 ("Add linux-next specific files for 20260828")

Changes in v4:
- Rebase onto next-20260828.
- Add MT8189 SMI common, sub-common and LARB binding compatibles.
- Place the DT binding update before the driver update.
- Drop Reviewed-by tags from AngeloGioacchino Del Regno and Yong Wu
because the patches changed materially.
- Update the MT8189 LARB OSTD settings to avoid zero values terminating
the existing Gen2 configuration loop.
- Link to v3:
https://lore.kernel.org/all/20260722-8189-smi-support-v3-0-ae00e13deeac@xxxxxxxxxxxx/

Changes in v3:
- Change the minimum clock number of smi-sub-common to 3.
- Link to v2:
