Subject: [PATCH v2 0/7] drivers/soc: Add Aspeed XDMA Engine Driver
Date: Mon, 20 May 2019 15:19:18 -0500 [thread overview]
Message-ID: <1558383565-11821-1-git-send-email-eajames@linux.ibm.com> (raw)
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.
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
