13 The OMAP family of SoCs usually have one or more slave processor sub-systems
14 that are used to offload some of the processor-intensive tasks, or to manage
17 The processor cores in the sub-system are usually behind an IOMMU, and may
18 contain additional sub-modules like Internal RAM and/or ROMs, L1 and/or L2
21 The OMAP SoCs usually have a DSP processor sub-system and/or an IPU processor
22 sub-system. The DSP processor sub-system can contain any of the TI's C64x,
23 C66x or C67x family of DSP cores as the main execution unit. The IPU processor
24 sub-system usually contains either a Dual-Core Cortex-M3 or Dual-Core
25 Cortex-M4 processors.
27 Each remote processor sub-system is represented as a single DT node. Each node
29 the host processor (MPU) to perform the device management of the remote
30 processor and to communicate with the remote processor. The various properties
36 image. Examples of variable properties include 'mboxes', 'memory-region',
37 'timers', 'watchdog-timers' etc.
