Mainline Status

• DMA Client driver (axidmatest and vdmatest - these are xilinx specific dma client driver and not streamable)

Change Log

2020.2

• MCDMA fixes (SG capability, usage of xilinx_aximcdma_tx_segment) 
• Add missing check for empty list in xilinx_dma_tx_status
• use readl_poll_timeout_atomic variant

2aefe65f2861 dmaengine: xilinx_dma: Add missing check for empty list
d2798ec3512e dmaengine: xilinx_dma: use readl_poll_timeout_atomic variant

2020.1

• Fix dma channel node order dependency.
• MCDMA IP support.
• 5.4 kernel upgrade (Merge tag 'dmaengine-5.3-rc1' of slave tree + xilinx tree rebase patches)

Commits:

b6848e6 dmaengine: xilinx_dma: In dma channel probe fix node order dependency
87e34b2 dmaengine: xilinx_dma: Extend dma_config structure to store max channel count

47ebe00 Merge tag 'dmaengine-5.3-rc1' of slave tree

2019.2

• Fix SG internal error in cdma prep_dma_sg mode.
• Clear desc_pendingcount in xilinx_dma_reset.
• Check for both idle and halted state in axidma stop.
• Residue calculation and reporting.
• Remove cdmatest client. Now onwards we have to use generic dmatest client for cdma validation.
