From 852ff5fea9eb6a9799f1881d6df2cd69a9e6eed5 Mon Sep 17 00:00:00 2001 From: David Woods Date: Fri, 26 May 2017 17:53:20 -0400 Subject: mmc: dw_mmc: Use device_property_read instead of of_property_read Using the device_property interfaces allows the dw_mmc driver to work on platforms which run on either device tree or ACPI.
