J784S4 has a dedicated BCDMA controller for the Camera Serial Interface. Events from the BCDMA controller instance are routed through the main UDMA interrupt aggregator as unmapped events. Add the node for the DMA controller and keep it disabled by default. See J784S4 Technical Reference Manual (SPRUJ52) for further details: http://www.ti.com/lit/zip/spruj52Signed-off-by:

Two carveout reserved memory nodes each have been added for each of the C71x DSP for the TI K3 AM69 SK boards. These nodes are assigned to the respective rproc device nodes as well. The first region will be used as the DMA pool for the rproc device, and the second region will furnish the static carveout regions for the firmware memory. The current carveout addresses and sizes are defined statically for each device. The C71x DSP processor supports a MMU called CMMU, but is not currently supported and as such requires the exact memory used by the firmware to be set-aside. Signed-off-by:

Two carveout reserved memory nodes each have been added for each of the R5F remote processor device within both the MCU and MAIN domains for the TI K3 AM69 SK boards. These nodes are assigned to the respective rproc device nodes as well. The first region will be used as the DMA pool for the rproc device, and the second region will furnish the static carveout regions for the firmware memory. The current carveout addresses and sizes are defined statically for each device. The R5F processors do not have an MMU, and as such require the exact memory used by the firmwares to be set-aside. The firmware images do not require any RSC_CARVEOUT entries in their resource tables either to allocate the memory for firmware memory segments. Note that the R5F1 carveouts are needed only if the R5F cluster is running in Split (non-LockStep) mode. The reserved memory nodes can be disabled later on if there is no use-case defined to use the corresponding remote processor. Signed-off-by:

The K3 J721S2 SoCs have two C71x DSP subsystems in MAIN voltage domain. The C71x DSPs are 64 bit machine with fixed and floating point DSP operations. Similar to the R5F remote cores, the inter-processor communication between the main A72 cores and these DSP cores is achieved through shared memory and Mailboxes. The following firmware names are used by default for these DSP cores, and can be overridden in a board dts file if desired: MAIN C71_0 : j721s2-c71_0-fw MAIN C71_1 : j721s2-c71_1-fw Signed-off-by: -

The J721S2 SoCs have 2 dual-core Arm Cortex-R5F processor (R5FSS) subsystems/clusters in MAIN voltage domain. Each of these can be configured at boot time to be either run in a LockStep mode or in an Asymmetric Multi Processing (AMP) fashion in Split-mode. These subsystems have 64 KB each Tightly-Coupled Memory (TCM) internal memories for each core split between two banks - ATCM and BTCM (further interleaved into two banks). The TCMs of both Cores are combined in LockStep-mode to provide a larger 128 KB of memory, but otherwise are functionally similar to those on J721E SoCs. Add the DT nodes for the MAIN domain R5F cluster/subsystems, the two R5F cores are added as child nodes to each of the R5F cluster nodes. The clusters are configured to run in LockStep mode by default, with the ATCMs enabled to allow the R5 cores to execute code from DDR with boot-strapping code from ATCM. The inter-processor communication between the main A72 cores and these processors is achieved through shared memory and Mailboxes. The following firmware names are used by default for these cores, and can be overridden in a board dts file if desired: MAIN R5FSS0 Core0: j721s2-main-r5f0_0-fw (both in LockStep & Split mode) MAIN R5FSS0 Core1: j721s2-main-r5f0_1-fw (needed only in Split mode) MAIN R5FSS1 Core0: j721s2-main-r5f1_0-fw (both in LockStep & Split mode) MAIN R5FSS1 Core1: j721s2-main-r5f1_1-fw (needed only in Split mode) Signed-off-by:

Currently J721E defines only the main_esm in DTS. Add node for mcu_esm as well. According to J721E TRM (12.11.2.2 ESM Environment) [1], we see that the interrupt line from ESMi (main_esm) is routed to MCU_ESM (mcu_esm). This is MCU_ESM0_LVL_IN_95 with interrupt ID 95. Configure mcu_esm accordingly so that errors from main_esm are routed to mcu_esm and handled. [1] https://www.ti.com/lit/zip/spruil1Signed-off-by:
