From 8c7634c0ee4e2b62a361cc0285418e201d162f37 Mon Sep 17 00:00:00 2001 From: Peter Crosthwaite Date: Mon, 1 Dec 2014 10:25:49 +1000 Subject: arm: dts: zynq: Move crystal freq. to board level 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).
