Subject: [PATCH v3 0/8] drivers/soc: Add Aspeed XDMA Engine Driver
Date:   Wed, 29 May 2019 13:10:00 -0500
Message-Id: <1559153408-31190-1-git-send-email-eajames@linux.ibm.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The XDMA engine embedded in the AST2500 SOC performs PCI DMA operations
between the SOC (acting as a BMC) and a host processor in a server.

This series adds a driver to control the XDMA engine in order to easily
perform DMA operations to and from the host processor.

Changes since v2:
 - Switch to one pci device config sysfs file
 - Add documentation for pci device config sysfs file
 - Add module parameter for pci device config
 - Switch to genalloc instead of custom allocator
 - Fix alignment of user structure
 - Cleaned up debugfs functions

I previously sent this series v1 to drivers/misc, but I'm now fairly certain
it belongs in drivers/soc, especially since the other Aspeed drivers have been
moved to soc.

Changes since v1:
 - Correct the XDMA command pitch
 - Don't use packed for the aspeed_xdma_op structure
 - Correct the SCU PCI config change
