[PATCH v8 0/2] Add Intel LGM SoC DMA support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add DMA controller driver for Lightning Mountain (LGM) family of SoCs.

The main function of the DMA controller is the transfer of data from/to any
peripheral to/from the memory. A memory to memory copy capability can also
be configured. This ldma driver is used for configure the device and channnels
for data and control paths.

These controllers provide DMA capabilities for a variety of on-chip
devices such as SSC, HSNAND and GSWIP.

-------------
Future Plans:
-------------
LGM SOC also supports Hardware Memory Copy engine.
The role of the HW Memory copy engine is to offload memory copy operations
from the CPU.
