v3:
1. Added Documentation for new flag 2. Changed the flag description
v2:
1. Added DMA_PREP_CMD flag and used the same for BAM DMA command descriptor 2. Removed custom mapping API patches
v1:
https://www.spinics.net/lists/dmaengine/msg12009.html
These patches mainly add the support for QCOM BAM command descriptor implementing BAM DMA support for some QCOM peripherals like QPIC NAND/LCD.
Currently there is no flag in DMA API which tells the DMA controller that the passed data is in command descriptor format so added the flag in DMA API for this.
Abhishek Sahu (3): dmaengine: add DMA_PREP_CMD for non-Data descriptors. dmaengine: qcom: bam_dma: wrapper functions for command descriptor dmaengine: qcom: bam_dma: add command descriptor flag
