Subject: [PATCH v7 0/3] dmaengine: APM X-Gene SoC DMA engine driver support
Date: Thu, 12 Mar 2015 16:45:18 +0530	[thread overview]
Message-ID: <1426158921-8987-1-git-send-email-rsahu@apm.com> (raw)

This patch set implements the APM X-Gene SoC DMA driver support to offload
the DMA operations such as memory copy(memcpy), scatter gather memory copy,
raid5 xor and raid6 p+q.

v7 changes:
	1. Added raid5 xor offload support.
	2. Added raid6 p+q offload support.
v6 changes:
	1. Maintained sw queue for pending, running, and completed
	   requests. Used link list as queue.
	2. Fixed issue_pending and tx_submit routines.
	3. Fixed prep_dma routines.
	4. Fixed free_irqs.

v5 changes:
	1. Minor changes in coding style.
	2. Added DMA_CTRL_ACK flag initialization
v4 changes:
	1. Fixed dma-ranges property on DTS.
