The initial version of this driver will only support slave DMA operations between system memory and peripherals. Flow control via the CRCI (client rate control interface) is supported and can be configured via device tree configuration. Flow control usage is required for some peripheral devices. Changes since v1: - Fixed various review comments - Fixed some descriptor programming issues. - Added single descriptors to support sub burst length transactions. Selection of single or box descriptors depends on the sg length and burst size. - Removed use of crci in the dmas property. CRCI is now designated via the slave_config structure and will be stored in slave_id.
