Based on tag: next-20240821, linux-next/master Refer to the discussion in the following link: https://lore.kernel.org/all/CAFGrd9qZhObQXvm2_abqaX83xMLqxjQETB2=wXpobDWU1CnvkA@xxxxxxxxxxxxxx/ https://lore.kernel.org/all/CAPDyKFpokXV2gJDgowbixTvOH_5VL3B5H8eyhP+KJ5Fasm2rFg@xxxxxxxxxxxxxx/ SMI clamp and reset operations should be implemented in SMI driver instead of PM driver. When we enable/disable power domain, the SMI LARBs linked to this power domain could be affected by the bus glitch. To avoid this issue, SMI need to apply clamp and reset opereations. These patches mainly add these functions: 1) Register genpd callback for SMI LARBs and handle this power domain status change into SMI driver. 2) Add SMI reset control driver to implement SMI reset opereations. 3) Add bindings for describing the reset control regmap and SMI Sub Common. friday.yang (4): dt-bindings: memory: mediatek: Add mt8188 SMI reset control binding dt-bindings: memory: mediatek: Add smi-sub-common property for reset memory: mtk-smi: mt8188: Add SMI clamp function reset: mediatek: Add reset control driver for SMI .../mediatek,smi-common.yaml | 2 + .../memory-controllers/mediatek,smi-larb.yaml | 22 +++ .../bindings/reset/mediatek,smi-reset.yaml | 46 ++++++ drivers/memory/mtk-smi.c | 148 ++++++++++++++++- drivers/reset/Kconfig | 9 ++ drivers/reset/Makefile | 1 + drivers/reset/reset-mediatek-smi.c | 152 ++++++++++++++++++ include/dt-bindings/reset/mt8188-resets.h | 11 ++ 8 files changed, 389 insertions(+), 2 deletions(-) create mode 100644 Documentation/devicetree/bindings/reset/mediatek,smi-reset.yaml create mode 100644 drivers/reset/reset-mediatek-smi.c -- 2.46.0
