This subsystem is provided for the use cases like the implementation of custom peripheral interfaces, offloading of tasks from the other processor cores of the SoC, etc. The subsystem includes many accelerators for data processing like multiplier and multiplier-accumulator. It also has peripherals like UART, MII/RGMII, MDIO, etc. Every ICSSG core includes two 32-bit load/store RISC CPU cores called PRUs. The above features allow it to be used for implementing custom firmware based peripherals like ethernet. This series adds the YAML documentation and the driver with basic EMAC support for TI AM654 Silicon Rev 2 SoC with the PRU_ICSSG Sub-system. running dual-EMAC firmware. This currently supports basic EMAC with 1Gbps and 100Mbps link. 10M and half-duplex modes are not yet supported because they require the support of an IEP, which will be added later. Advanced features like switch-dev and timestamping will be added later. This series depends on two patch series that are not yet merged, one in the remoteproc tree and another in the soc tree. the first one is titled Introduce PRU remoteproc consumer API and the second one is titled Introduce PRU platform consumer API. Both of these are required for this driver. To explain this dependency and to get reviews, I had earlier posted all three of these as an RFC[1], this can be seen for understanding the dependencies. I then posted the remoteproc[2] and soc[3] series seperately to their respective trees.
