From 7657c3a7d4bd42b832af5d6bb0e0e9bdba82d44d Mon Sep 17 00:00:00 2001 From: Albert Herranz Date: Thu, 17 Dec 2009 15:27:20 -0800 Subject: sdhci-of: reorganize driver to support additional hardware This patch breaks down sdhci-of into a core portion and a eSDHC portion, clearing the path to easily support additional hardware using the same OF driver.
