Subject: [PATCH v3 0/6]  Add a PRU remoteproc driver

Hi All,

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.

The K3 AM65x amd J721E SoCs have the next generation of the PRU-ICSS IP,
commonly called ICSSG. The ICSSG IP on AM65x SoCs has two PRU cores,
two auxiliary custom PRU cores called Real Time Units (RTUs). The K3
AM65x SR2.0 and J721E SoCs have a revised version of the ICSSG IP, and
include two additional custom auxiliary PRU cores called Transmit PRUs
(Tx_PRUs).

This series contains the PRUSS remoteproc driver together with relevant
dt-binding. This is the 3rd foundation component for PRUSS subsystem, the
previous two 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

The following is a v3 version of the series. Please see the individual patches
for exact changes in each patch, following are the main changes from v2[1]:
- Add Reviewed-by: Mathieu Poirier <mathieu.poirier@linaro.org> for 4 patches
after introducing minor fixes/improvements.
- Adjust the patch title to latest remoteproc subsystem convention:
s/remoteproc\/pru:/remoteproc:pru:/ as suggested by Suman.
