12description: |
13  A PRU application/consumer/user node typically uses one or more PRU device
14  nodes to implement a PRU application/functionality. Each application/client
15  node would need a reference to at least a PRU node, and optionally define
16  some properties needed for hardware/firmware configuration. The below
17  properties are a list of common properties supported by the PRU remoteproc
18  infrastructure.
19
20  The application nodes shall define their own bindings like regular platform
21  devices, so below are in addition to each node's bindings.

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