[PATCH 0/3] ARM: dts: aspeed: Enable SD controllers

[Andrew Jeffery]

Hello,

This series describes the ASPEED SD controller in relevant devicetree files,
enabling the MMC slots on the AST2500 EVB and Swift machines.

Please review!

[PATCH 1/3] ARM: dts: aspeed: Describe SD controller in DTSIs

[Andrew Jeffery]

The AST2400 and AST2500 both share the same SD controller, at the same
location in the physical address space and the same hardware interrupt,
with the same clock configurations.
