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.
