[PATCH 0/2] nord : llcc : Adding LLCC dt bindings and SCT configurations

Posted by Anurag Pateriya 2 weeks, 1 day ago

This series adds Last Level Cache Controller (LLCC) support for the Nord SoC.

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
