From 70f6d39433d3d597adeac3d4c84b3a58b86cd2d3 Mon Sep 17 00:00:00 2001 From: Jaehoon Chung Date: Wed, 29 Jun 2016 19:46:18 +0900 Subject: mmc: exynos_dw_mmc: use the 4bit bus-width by default If there is not "samsung,bus-width" property, use the 4bit buswidth by default. Almost all Exnyos SoCs support at least 4bit buswidth.
