+title: TI Programmable Realtime Unit (PRU) cores
+
+maintainers:
+ - Suman Anna <s-anna@ti.com>
+
+description: |
+ Each Programmable Real-Time Unit and Industrial Communication Subsystem
+ (PRU-ICSS or PRUSS) has two 32-bit load/store RISC CPU cores called
+ Programmable Real-Time Units (PRUs), each represented by a node. Each PRU
+ core has a dedicated Instruction RAM, Control and Debug register sets, and
+ use the Data RAMs present within the PRU-ICSS for code execution.
+
+ The K3 SoCs containing ICSSG v1.0 (eg: AM65x SR1.0) also have two Auxiliary
+ PRU cores called RTUs with slightly different IP integration. The K3 SoCs
+ containing the revised ICSSG v1.1 (eg: J721E, AM65x SR2.0) have an extra two
+ auxiliary Transmit PRU cores called Tx_PRUs that augment the PRUs. Each RTU
+ or Tx_PRU core can also be used independently like a PRU, or alongside a
+ corresponding PRU core to provide/implement auxiliary functionality/support.
+
+ Each PRU, RTU or Tx_PRU core node should be defined as a child node of the
+ corresponding PRU-ICSS node. Each node can optionally be rendered inactive by
+ using the standard DT string property, "status".
+
+ Please see the overall PRU-ICSS bindings document for additional details
+ including a complete example,
+ Documentation/devicetree/bindings/soc/ti/ti,pruss.yaml
