To avoid this issue, SMI need to apply clamp and reset opereations. This patch mainly add these functions: 1) Register genpd callback for SMI LARBs and handle this power domain status change in SMI driver. 2) Add bindings to support SMI Sub Common for MT8188. 3) Add bindings to support SMI larbs reset opearation. Changes v3: - Remove redundant descriptions for 'resets' and 'reset-names' - Modify the requirements for 'resets' and 'reset-names' - Rename 'mtk_smi_larb_parse_clamp' to 'mtk_smi_larb_parse_clamp_optional' - Rename 'mtk_smi_larb_parse_reset' to 'mtk_smi_larb_parse_reset_optional' - Merge 'mtk_smi_larb_clamp_protect_enable' and 'mtk_smi_larb_clamp_protect_disble' into one function - Modify the definition for mtk_smi_larb_clamp_port_mt8188, use 'larbid' as the index of the array - Use 'syscon_regmap_lookup_by_phandle' instead of 'device_node_to_regmap' - Do Not parse 'resets', just check the return value of 'devm_reset_control_get' - Add 'has_gals' flag for 'mtk_smi_sub_common_mt8188' v2: https://lore.kernel.org/lkml/20241120063701.8194-2-friday.yang@mediatek.com/ https://lore.kernel.org/lkml/20241120063701.8194-3-friday.yang@mediatek.com/ friday.yang (2): dt-bindings: memory: mediatek: Add support for SMI reset and clamp memory: mtk-smi: mt8188: Add support for SMI reset and clamp .../mediatek,smi-common.yaml | 2 + .../memory-controllers/mediatek,smi-larb.yaml | 20 +++ drivers/memory/mtk-smi.c | 141 +++++++++++++++++- 3 files changed, 159 insertions(+), 4 deletions(-) --- 2.46.0
