Subject: [PATCH v2 00/12] Aspeed: Add SCU interrupt controller and XDMA engine drivers
Date:   Thu,  5 Dec 2019 11:15:00 -0600
Message-Id: <1575566112-11658-1-git-send-email-eajames@linux.ibm.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This series first adds a driver to control the interrupt controller provided by
the System Control Unit (SCU) on the AST2500 and AST2600 SOCs. The interrupts
made available are necessary for the control of the XDMA engine embedded in the
same Aspeed SOCs.
This series then adds a driver to control the XDMA engine. This driver was
previously sent to the list without support for the AST2600, and has been
refactored significantly to enable that support. The XDMA engine performs
automatic DMA operations between the Aspeed SOC (acting as a BMC) and a host
processor.

Changes since v1:
 - See individual patches
 - In summary, first the irqchip driver switched to use the parent SCU regmap
   rather than iomapping it's register. Secondly, the XDMA initialization
   switched to use properties from the device tree rather than dynamically
   calculate memory spaces, and system config.
