+title: Common TI PRU Consumer Binding

+
+description: |
+ A PRU application/consumer/user node typically uses one or more PRU device
+ nodes to implement a PRU application/functionality. Each application/client
+ node would need a reference to at least a PRU node, and optionally define
+ some properties needed for hardware/firmware configuration. The below
+ properties are a list of common properties supported by the PRU remoteproc
+ infrastructure.
+
+ The application nodes shall define their own bindings like regular platform
+ devices, so below are in addition to each node's bindings.

+ array of values for the GP_MUX_SEL under PRUSS_GPCFG register for a PRU.
+ This selects the internal muxing scheme for the PRU instance. Values
+ should correspond to the PRU cores listed in the 'ti,prus' property. The
+ GP_MUX_SEL setting is a per-slice setting (one setting for PRU0, RTU0,
+ and Tx_PRU0 on K3 SoCs). Use the same value for all cores within the
+ same slice in the associative array. If the array size is smaller than
+ the size of 'ti,prus' property, the default out-of-reset value (0) for the
+ PRU core is used.
