[PATCH v2 08/12] ARM: dts: aspeed: ast2500: Add XDMA Engine

Fri Dec 6 04:15:08 AEDT 2019


Add a node for the XDMA engine with all the necessary information. Also
make the EDAC node compatible with syscon.

Signed-off-by: Eddie James <eajames at linux.ibm.com>

Changes since v1:
 - Add syscon compatible to the SDRAM controller so we can grab it in the
   XDMA driver
 - Add the new properties to the XDMA node
