From 29bcecbb93b009e650dfdf9e6a1ff6efadc871bc Mon Sep 17 00:00:00 2001
From: Vladimir Barinov <vladimir.barinov@cogentembedded.com>
Date: Thu, 10 Aug 2017 08:41:53 +0300
Subject: [PATCH] arm64: dts: renesas: ulcb: use versaclock for DU RGB and LVDS
This allows to chgange preprogrammed clock in Versa5 clock
generator.
DU has PLL that is not too accurate, hence use prescaled value by VC5.
