dma: ti-edma3: introduce edma3 driver
The EDMA3 controller’s primary purpose is to service data transfers
that you program between two memory-mapped slave endpoints on the device.
Typical usage includes, but is not limited to the following:
- Servicing software-driven paging transfers (e.g., transfers from external
memory, such as SDRAM to internal device memory, such as DSP L2 SRAM)
- Servicing event-driven peripherals, such as a serial port
- Performing sorting or sub-frame extraction of various data structures
- Offloading data transfers from the main device DSP(s)
- See the device-specific data manual for specific peripherals that are
accessible via the EDMA3 controller
