7 title: TI PRU Consumer Common Properties
10 - Suman Anna <s-anna@ti.com>
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
20 The application nodes shall define their own bindings like regular platform
21 devices, so below are in addition to each node's bindings.

37 firmwares for the PRU cores, the default firmware for the core from
38 the PRU node will be used if not provided. The firmware names should

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
