Subject[PATCH v5 0/6] Introduce PRU remoteproc consumer API
Date
This is the v5 of the patch series [1]. The 6th patch in the series was
added in v4 and it had some checkpatch.pl errors which are removed here.

I have posted two more patch series that depend on this series, one to
the soc tree and another to the networking tree. I had sent all the 3
series, including this one as RFC [2] to get comments and to explain the
dependencies.

The Programmable Real-Time Unit and Industrial Communication Subsystem
(PRU-ICSS or simply PRUSS) on various TI SoCs consists of dual 32-bit
RISC cores (Programmable Real-Time Units, or PRUs) for program execution.

There are 3 foundation components for PRUSS subsystem: the PRUSS platform
driver, the PRUSS INTC driver and the PRUSS remoteproc driver. All were
already merged and can be found under:
1) drivers/soc/ti/pruss.c
Documentation/devicetree/bindings/soc/ti/ti,pruss.yaml
2) drivers/irqchip/irq-pruss-intc.c
Documentation/devicetree/bindings/interrupt-controller/ti,pruss-intc.yaml
3) drivers/remoteproc/pru_rproc.c
Documentation/devicetree/bindings/remoteproc/ti,pru-rproc.yaml

The programmable nature of the PRUs provide flexibility to implement custom
peripheral interfaces, fast real-time responses, or specialized data handling.
Example of a PRU consumer drivers will be:
- Software UART over PRUSS
- PRU-ICSS Ethernet EMAC

In order to make usage of common PRU resources and allow the consumer drivers to
configure the PRU hardware for specific usage the PRU API is introduced.
