Serge Semin 0f9d5f008e dmaengine: dw: Initialize max_sg_burst capability ... Multi-block support provides a way to map the kernel-specific SG-table so the DW DMA device would handle it as a whole instead of handling the SG-list items or so called LLP block items one by one. So if true LLP list isn't supported by the DW DMA engine, then soft-LLP mode will be utilized to load and execute each LLP-block one by one. The soft-LLP mode of the DMA transactions execution might not work well for some DMA consumers like SPI due to its Tx and Rx buffers inter-dependency. Let's initialize the max_sg_burst DMA channels capability based on the nollp flag state. If it's true, no hardware accelerated LLP is available and max_sg_burst should be set with 1, which means that the DMA engine can handle only a single SG list entry at a time. If noLLP is set to false, then hardware accelerated LLP is supported and the DMA engine can handle infinite number of SG entries in a single DMA transaction.
