From e477f4bdd40496a53f7c2c4290ef4ba16ca4d869 Mon Sep 17 00:00:00 2001 From: Yangbo Lu <yangbo.lu@nxp.com> Date: Tue, 16 Feb 2016 10:54:41 +0800 Subject: [PATCH] armv8/fsl-lsch2: fix sdhc clock frequency value The eSDHC could select to use platform clock or peripheral clock to generate SD clock. The default selection is platform clock. So, fix the clock frequency value that's calculated for eSDHC.
