[PATCH V2 2/3] arm: dts: zynq: Move crystal freq. to board level

[Peter Crosthwaite]

The fact that all supported boards use the same 33MHz crystal is a
co-incidence. The Zynq PS support a range of crystal freqs so the
hardcoded setting should be removed from the dtsi. Re-implement it
on the board level.

This prepares support for Zynq boards with different crystal
frequencies (e.g. the Digilent ZYBO).

Changed since v1:
Alphabetize node ordering (Soren review)

Im guessing long term this should be converted to a fixed clock. But
I think this at least steps in that direction.

[PATCH V2 3/3] arm: dts: zynq: Add Digilent ZYBO board

[Peter Crosthwaite]

Add a DTS describing the Digilent ZYBO board. Similar to ZED but with
a 50MHz crystal instead of 33MHz.

Hi Peter,

The patches look all good to me. But you may want to check your CC
lists. I think at least the DT list should be included.

For the whole series:
