From 087bfe67ac2555c37b257335424b7c193d7f6afd Mon Sep 17 00:00:00 2001 From: Yangbo Lu Date: Thu, 23 May 2019 11:05:45 +0800 Subject: [PATCH] armv8: fsl-lsch3: add clock support for the second eSDHC Layerscape began to use two eSDHC controllers, for example, LS1028A. They are same IP block with same reference clock. This patch is to add clock support for the second eSDHC.
