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.
