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.
