The K3 AM65x family of SoCs have the next generation of the PRU-ICSS processor subsystem, commonly referred to as ICSSG. Each ICSSG processor subsystem on AM65x SR1.0 contains two primary PRU cores and two new auxiliary PRU cores called RTUs. The AM65x SR2.0 SoCs have a revised ICSSG IP that is based off the subsequent IP revision used on J721E SoCs. This IP instance has two new custom auxiliary PRU cores called Transmit PRUs (Tx_PRUs) in addition to the existing PRUs and RTUs. Each RTU and Tx_PRU cores have their own dedicated IRAM (smaller than a PRU), Control and debug feature sets, but is different in terms of sub-modules integrated around it and does not have the full capabilities associated with a PRU core. The RTU core is typically used to aid a PRU core in accelerating data transfers, while the Tx_PRU cores is normally used to control the TX L2 FIFO if enabled in Ethernet applications. Both can also be used to run independent applications. The RTU and Tx_PRU cores though share the same Data RAMs as the PRU cores, so the memories have to be partitioned carefully between different applications. The new cores also support a new sub-module called Task Manager to support two different context thread executions. The driver currently supports the AM65xx SoC Signed-off-by: Keerthy <j-keerthy@ti.com> Signed-off-by: Suman Anna <s-anna@ti.com> Signed-off-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Link: https://lore.kernel.org/r/20210622063431.3151-3-lokeshvutla@ti.com
