The Cadence IP expects a specific format (detailed in the Documentation). Add helpers to copy the data into the DMA buffer. The crc8 table is for now only used by the Cadence driver. This table might be moved to a common module at a later point if needed by other controller implementations.

SoundWire is a 2-Pin interface with data and clock line ratified
|
|
by the MIPI Alliance. SoundWire is used for transporting data
|
|
typically related to audio functions. SoundWire interface is

systems. Say Y to enable this subsystem, N if you do not have such
