> The below patch series are to support AxiDMA running on Intel KeemBay SoC.
> The base driver is dw-axi-dmac but code refactoring is needed, for example:
> - Support YAML Schemas DT binding.
> - Replacing Linked List with virtual descriptor management.
> - Remove unrelated hw desc stuff from dma memory pool.
> - Manage dma memory pool alloc/destroy based on channel activity.
> - Support dmaengine device_sync() callback.
> - Support dmaengine device_config().
> - Support dmaegnine device_prep_slave_sg().
> - Support dmaengine device_prep_dma_cyclic().
> - Support of_dma_controller_register().
> - Support burst residue granularity.
> - Support Intel KeemBay AxiDMA registers.
> - Support Intel KeemBay AxiDMA device handshake.
> - Support Intel KeemBay AxiDMA BYTE and HALFWORD device operation.
> - Add constraint to Max segment size.
