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.
