[PATCH 0/3] AM64: Add SERDES DT bindings

[PATCH 0/3] AM64: Add SERDES DT bindings

[Kishon Vijay Abraham I]

Patch series adds device tree bindings to support SERDES in AM64
platform.

This is split from [1] since this binding is also required for AM64
USB DT patches to be merged.

Vinod,

Once the 1st patch of the series is reviewed by Rob, can you merge and
prepare a immutable tag to be used by Nishant Menon so that he can merge
USB3 DT patches.

Changes from [1]:
*) Reverted back to adding compatible under enum.

Now that Rob has Acked the 1st patch, can you prepare an immutable tag
for Nishant Menon on this series.

AM64 SERDES driver changes [1] can also be merged after this.

Thank You
