-Qualcomm Technologies, Inc. DPU RSC
-
-Snapdragon Display Engine implements display rsc to driver
-display core to different modes for power saving
-
-Required properties
-- compatible: Must be "qcom,dpu-rsc"
-- reg: Offset and length of the register set for
- the device.
-- reg-names: Names to refer to register sets related
- to this device
-
-Optional properties:
-- clocks: List of phandles for clock device nodes
- needed by the device.
-- clock-names: List of clock names needed by the device.
-- vdd-supply: phandle for vdd regulator device node.
-- qcom,dpu-rsc-version: U32 property represents the rsc
version. It helps to
- select correct sequence for dpu rsc based on
version.
-- qcom,dpu-dram-channels: U32 property represents the number of channels
in the
- Bus memory controller.
-- qcom,dpu-num-nrt-paths: U32 property represents the number of
non-realtime
- paths in each Bus Scaling Usecase. This value
depends on
- number of AXI ports that are dedicated to
non-realtime VBIF
- for particular chipset.
- These paths must be defined after rt-paths in
- "qcom,msm-bus,vectors-KBps" vector request.
-
-Bus Scaling Subnodes:
-- qcom,dpu-data-bus: Property to provide Bus scaling for data bus
access for
- dpu blocks.
-- qcom,dpu-llcc-bus: Property to provide Bus scaling for data bus
access for
- mnoc to llcc.
-- qcom,dpu-ebi-bus: Property to provide Bus scaling for data bus
access for
- llcc to ebi.
-
-Bus Scaling Data:
-- qcom,msm-bus,name: String property describing client name.
-- qcom,msm-bus,active-only: Boolean context flag for requests in active or
- dual (active & sleep) contex
-- qcom,msm-bus,num-cases: This is the number of Bus Scaling use cases
- defined in the vectors property.
-- qcom,msm-bus,num-paths: This represents the number of paths in each
- Bus Scaling Usecase.
-- qcom,msm-bus,vectors-KBps: * A series of 4 cell properties, with a format
- of (src, dst, ab, ib) which is defined at
-
Documentation/devicetree/bindings/arm/msm/msm_bus.txt
- * Current values of src & dst are defined at
- include/linux/msm-bus-board.h

- <0xaf30000 0x3fd4>;
