From d552f675fb313eb020c384c03307ecfb83dce1ad Mon Sep 17 00:00:00 2001 From: Jean-Christophe Dubois Date: Wed, 16 Mar 2016 17:06:00 +0000 Subject: [PATCH] i.MX: Add the CLK_IPG_HIGH clock EPIT, GPT and other i.MX timers are using "abstract" clocks among which a CLK_IPG_HIGH clock. On i.MX25 and i.MX31 CLK_IPG and CLK_IPG_HIGH are mapped to the same clock but on other SOC like i.MX6 they are mapped to distinct clocks. This patch add the CLK_IPG_HIGH to prepare for SOC where these 2 clocks are different.
