[PATCH v3 0/3] Support for QCOM BAM DMA command descriptor
From: Abhishek Sahu
Date: Tue Aug 01 2017 - 10:12:04 EST
1. Added Documentation for new flag
2. Changed the flag description
1. Added DMA_PREP_CMD flag and used the same for BAM DMA
2. Removed custom mapping API patches
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.

dmaengine: add DMA_PREP_CMD for non-Data descriptors.
dmaengine: qcom: bam_dma: wrapper functions for command descriptor
