Subject[PATCH v3 0/3] Support for QCOM BAM DMA command descriptor
Date
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
