From de0970203091618834e4753c14d5169770797800 Mon Sep 17 00:00:00 2001
From: Vincent ABRIOU <vincent.abriou@st.com>
Date: Fri, 10 Jan 2014 11:02:33 +0100
Subject: [PATCH] modetest: add the possibility to select the refresh
frequency for a mode
When mode is selected we only give the name of the mode as parameter.
But sometime, two different modes have the same name but not
the same vrefresh frequency.
This patch give the possibility to select a mode by its name
and optionally by its refresh frequency.
