Programmable Realtime Unit (PRU) is basically a 32-bit RISC
processor available within TI's DA8XX SOCs. It consists of local
instruction and data RAM and also has access to SOC resources
via a Switched Central Resource (SCR).
There are two PRU's available within DA8XX SOC's PRUSS, hence providing
two execution cores. Devices/Protocols can be emulated on these utilizing
either both or only one of the PRUs independently.
The rational behind the MFD driver being the fact that multiple devices can
be implemented on the cores independently.
It's also possible, as in our case, to implement a single device on both
the PRU's resulting in improved load sharing.
A detailed description is also available here:
