The AM33xx SoCs contain a single PRU-ICSS instance and is represented by a pruss node and other child nodes. PRU-ICSS is supported only on AM3356+ SoCs though in the AM33xx family, so the nodes are added under the corresponding disabled interconnect target module node in the common am33xx-l4 dtsi file. The target module node should be enabled in only those derivative board files that use a SoC containing PRU-ICSS. The PRUSS subsystem node contains the entire address space. The various sub-modules of the PRU-ICSS are represented as individual child nodes (so platform devices themselves) of the PRUSS subsystem node. These include the two PRU cores and the interrupt controller. All the Data RAMs are represented within a child node of its own named 'memories' without any compatible. The Real Time Media Independent Interface controller (MII_RT), and the CFG sub-module are represented as syscon nodes. The PRUSS CFG module has a clock mux for IEP clock, this clk node is added under the CFG child node 'clocks'. The default source for this mux clock is the PRU_ICSS_IEP_GCLK clock. The DT nodes use all standard properties. The regs property in the PRU nodes define the addresses for the Instruction RAM, the Debug and Control sub-modules for that PRU core. The firmware for each PRU core is defined through a 'firmware-name' property. The default names for the firmware images for each PRU core are defined as follows (these can be adjusted either in derivative board dts files or through sysfs at runtime if required): PRU-ICSS PRU0 Core: am335x-pru1_0-fw PRU-ICSS PRU1 Core: am335x-pru1_1-fw Note: 1. There are few more sub-modules like the Industrial Ethernet Peripheral (IEP), MDIO, UART, eCAP that do not have bindings and so will be added in the future. 2. The PRUSS INTC on AM335x SoCs also connect the host interrupts 0 to TSC_ADC; 6 and 7 as possible DMA events, so use the 'ti,irqs-reserved' property in derivative board dts files _if_ any of them should not be handled by the host OS.

Each PRU-ICSS instance is represented by a pruss node and other child nodes. The nodes are added under the interconnect target module node in the common am4372 dtsi file. The PRU-ICSS instances are supported only on AM4376+ SoCs though in the AM437x family, so the interconnect target module node should be disabled in any derivative board dts file that uses AM4372 SoCs. The PRU-ICSS1 on AM437x is very similar to the PRUSS in AM33xx, except for variations in the RAM sizes, bus addresses and the number of interrupts coming into the MPU INTC (host interrupt 5 is routed to the other PRUSS instead of MPU). The PRUSS subsystem node contains the entire address space. The various sub-modules of the PRU-ICSS are represented as individual child nodes (so platform devices themselves) of the PRUSS subsystem node. These include the two PRU cores and the interrupt controller. All the Data RAMs are represented within a child node of its own named 'memories' without any compatible. The Real Time Media Independent Interface controller (MII_RT), and the CFG sub-module are represented as syscon nodes. The PRUSS CFG module has a clock mux for IEP clock, this clk node is added under the CFG child node 'clocks'. The default source for this mux clock is the PRU_ICSS_IEP_GCLK clock. The DT nodes use all standard properties. The regs property in the PRU nodes define the addresses for the Instruction RAM, the Debug and Control sub-modules for that PRU core. The firmware for each PRU core is defined through a 'firmware-name' property. The default names for the firmware images for each PRU core are defined as follows (these can be adjusted either in derivative board dts files or through sysfs at runtime if required): PRU-ICSS1 PRU0 Core: am437x-pru1_0-fw PRU-ICSS1 PRU1 Core: am437x-pru1_1-fw Note: 1. There are few more sub-modules like the Industrial Ethernet Peripheral (IEP), MDIO, UART, eCAP that do not have bindings and so will be added in the future. 2. The PRUSS INTC on AM437x SoCs also connect the host interrupt 0 to ADC0 and ADC1; 6 and 7 as possible DMA events, so use the 'ti,irqs-reserved' property in derivative board dts files _if_ any of them should not be handled by the host OS. Host interrupt 5 is already marked reserved as it is connected to the other PRUSS instance.

The PRUSS0 has less DRAM per PRU, and no Shared DRAM among other minor differences. The IEP and MII_RT modules even though present within the IP are not pinned out. This PRUSS0 instance has a weird SoC integration. It shares the same L3 OCP interconnect interface with PRUSS1, and also shares its reset line and clocks. Any external accesses from PRUSS0 requires the PRUSS1's PRUSS_SYSCFG register to be programmed properly. That said, it is its own IP instance (a cut-down version), and so it has been added as an independent node (sibling node to PRUSS1 node) and a child node of the corresponding PRUSS target module interconnect node. This allows the PRUSS0 instance to be enabled/disabled independently of the PRUSS1 instance. The nodes are added under the corresponding interconnect target module node in the common am4372 dtsi file. The PRU-ICSS instances are not supported on AM4372 SoC though in the AM437x family, so the interconnect target module node should be disabled in any derivative board dts file that uses AM4372 SoCs. The individual PRUSS node can be disabled in the corresponding board dts file if desired. The default names for the firmware images for each PRU core are defined as follows (these can be adjusted either in derivative board dts files or through sysfs at runtime if required): PRU-ICSS0 PRU0 Core: am437x-pru0_0-fw PRU-ICSS0 PRU1 Core: am437x-pru0_1-fw Note: 1. There are few more sub-modules like the Industrial Ethernet Peripheral (IEP), eCAP, UART, that do not have bindings and so will be added in the future. Only UART is pinned out, so others should be added in disabled state if added. 2. The PRUSS0 INTC on AM437x SoCs routes the host interrupt 5 to the other PRUSS1, so it is already marked reserved through the 'ti,irqs-reserved' property.

Davis" The PRU-ICSS1 instance on AM437x SoCs has a MDIO sub-module that can be used to control external PHYs associated with the Industrial Ethernet peripherals within the PRUSS. The MDIO module used within this PRU-ICSS is an instance of the MDIO Controller used in TI Davinci SoCs. The same bus frequency of 1 MHz is chosen as the regular MDIO node. Note that there is no MDIO node added to the smaller PRU-ICSS0 instance as the MDIO pins are not pinned out. The node is added and enabled in the common am4372.dtsi file by default, and disabled in all the existing AM437x board dts files. This node needs pinctrl lines, and so should be enabled only on boards where they are actually wired and pinned out for PRUSS Ethernet. Any new board dts file should disable these if they are not sure. Signed-off-by: Andrew F.

Each PRU-ICSS instance is represented by a pruss node and other child nodes. The two PRU-ICSSs are identical to each other. They are not supported on DRA7xx SoCs in general, so the nodes are added under the respective interconnect target module nodes in a common am57-pruss.dtsi file. The file is already included only in the AM57xx related board files. The PRU-ICSSs on AM57xx are very similar to the PRUSS in AM33xx and AM437x except for variations in the RAM sizes and the number of interrupts coming into the MPU INTC. The interrupt events into the PRU-ICSS also requires programming of the corresponding crossbars properly. The PRUSS subsystem node contains the entire address space. The various sub-modules of the PRU-ICSS are represented as individual child nodes (so platform devices themselves) of the PRUSS subsystem node. These include the two PRU cores and the interrupt controller. All the Data RAMs are represented within a child node of its own named 'memories' without any compatible. The Real Time Media Independent Interface controller (MII_RT), and the CFG sub-module are represented as syscon nodes. The PRUSS CFG module has a clock mux for IEP clock, this clk node is added under the CFG child node 'clocks'. The default source for this mux clock is the ICSS_IEP_CLK clock. The DT nodes use all standard properties. The regs property in the PRU nodes define the addresses for the Instruction RAM, the Debug and Control sub-modules for that PRU core. The firmware for each PRU core is defined through a 'firmware-name' property. The default names for the firmware images for each PRU core are defined as follows (these can be adjusted either in derivative board dts files or through sysfs at runtime if required): PRU-ICSS1 PRU0 Core: am57xx-pru1_0-fw PRU-ICSS1 PRU1 Core: am57xx-pru1_1-fw PRU-ICSS2 PRU0 Core: am57xx-pru2_0-fw PRU-ICSS2 PRU1 Core: am57xx-pru2_1-fw Note: 1. There are few more sub-modules like the Industrial Ethernet Peripheral (IEPs), MDIO, UART, eCAP that do not have bindings and so will be added in the future. 2. The PRUSS INTC on AM57xx SoCs also connect the host interrupts 6 and 7 as possible DMA events, so use the 'ti,irqs-reserved' property in derivative board dts files _if_ any of them should not be handled by the host OS.

The MDIO module used within the PRU-ICSS is an instance of the MDIO Controller used in TI Davinci SoCs. The same bus frequency of 1 MHz is chosen as the regular MDIO node. The nodes are added in the common am57-pruss.dtsi file and enabled by default, but are disabled in all the existing AM57xx board dts files. These nodes need pinctrl lines, and so should be enabled only on boards where they are actually wired and pinned out for PRUSS Ethernet. Any new board dts file should disable these if they are not sure. Signed-off-by: Suman Anna Signed-off-by: Andrew F.
