The purpose of the driver is to partition the system cache and program the settings such as priortiy, lines to probe while doing a look up in the system cache, low power related settings etc. The partitions are called cache slices. Each cache slice is associated with size and SCID(System Cache ID) The driver also provides API for clients to query the cache slice details, activate and deactivate them. The driver can be broadly classified into: * SOC specific driver: llcc-sdm845.c: Cache partitioning and cache slice properties for usecases on sdm845 that need to use system cache. * API : llcc-slice.c: Exports APIs to clients to query cache slice details, activate and deactivate cache slices. Register the child devices using platform APIs. Changes since v0: * Removed the syscon and simple-mfd approach * Updated the device tree nodes to mention LLCC as a single HW block * Moved llcc bank offsets from device tree and handled the offset in the driver. ckadabi@codeaurora.org (2): Documentation: Documentaion for qcom, llcc drivers: soc: Add LLCC driver .../devicetree/bindings/arm/msm/qcom,llcc.txt | 78 ++++ drivers/soc/qcom/llcc-sdm845.c | 120 ++++++ drivers/soc/qcom/llcc-slice.c | 460 +++++++++++++++++++++ include/linux/soc/qcom/llcc-qcom.h | 178 ++++++++ 4 files changed, 836 insertions(+) create mode 100644 Documentation/devicetree/bindings/arm/msm/qcom,llcc.txt create mode 100644 drivers/soc/qcom/llcc-sdm845.c create mode 100644 drivers/soc/qcom/llcc-slice.c create mode 100644 include/linux/soc/qcom/llcc-qcom.h -- The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, a Linux Foundation Collaborative Project
