Nord is a multi-cluster platform with four DDR slices, each containing four MACH9 LLCC banks, for a total of sixteen banks plus a shared broadcast OR/AND pair. The series consists of two patches: 1. dt-bindings: cache: qcom,llcc: Add Nord compatible - Updates the LLCC device tree binding to document Nord's sixteen-bank configuration - Raises maxItems for reg and reg-names from 14 to 18 to accommodate the additional banks and broadcast regions 2. soc: qcom: llcc: Add LLCC configuration for Nord - Adds the LLCC slice configuration table for Nord, derived from the Nord AU (Safe IVI) SCT table - Includes thirteen use cases with unique SCIDs and usecase IDs - Sets no_edac flag because the bootloader leaves LLCC EDAC registers locked Signed-off-by: Anurag Pateriya --- Anurag Pateriya (2): dt-bindings: cache: qcom,llcc: Add Nord compatible soc: qcom: llcc: Add LLCC configuration for Nord .../devicetree/bindings/cache/qcom,llcc.yaml | 55 +++++++- drivers/soc/qcom/llcc-qcom.c | 139 +++++++++++++++++++++ include/linux/soc/qcom/llcc-qcom.h | 2 + 3 files changed, 194 insertions(+), 2 deletions(-) --- base-commit: 693de981a44b0e7e3b6a73f0b0bcbae9c8d068e6 change-id: 20260910-nord_llcc-51aabc83f8fe Best regards, -- Anurag Pateriya
