Hello,

This series exposes some devicetree properties for tuning sample phase
delay in the Aspeed SD/eMMC controllers. The relevant register was
introduced on the AST2600 and is present for both the SD/MMC controller
and the dedicated eMMC controller.

Please review!

Joel: If Rob's happy with the binding change can you take the dts patch
through the aspeed dt tree?

Cheers,

Andrew
