| 12 | description: | |
| 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. |
