Hello,

This series implements support for the MMC core clk-phase-* devicetree bindings
in the Aspeed SD/eMMC driver. The relevant register was exposed on the AST2600
and is present for both the SD/MMC controller and the dedicated eMMC
controller.

v6 simply removes the typedef from v5 in favour of a struct containing the
phase array.

I've just done a quick build test of v6 given the small change and more
extensive testing done with v5. 

v5 can be found here:

Please review!

Cheers,

Andrew
