Subject: [PATCH] drivers: mmc: sdhci: update max frequency only if undefined
Date: Thu, 18 Jun 2015 12:57:07 +0530 [thread overview]
Message-ID: <1434612427-1758-1-git-send-email-suneel.garapati@xilinx.com> (raw)
f_max parameter of mmc structure is updated unconditionally.
If dt property max-frequency is assigned, this update is
overwriting the dt property value which is undesired.
