From 5ae70296c85f96a9969891d9de3410ebdf210b71 Mon Sep 17 00:00:00 2001 From: Philip Langdale Date: Sat, 15 Sep 2007 12:54:08 -0700 Subject: mmc: Disabler for Ricoh MMC controller Thanks to Matt Domsch and Rezwanul Kabir at Dell, we know how to disable the MMC controller on the multi-function Ricoh R5C832. The MMC controller needs to be disabled or it will steal MMC cards from the SD controller where they would otherwise be supported by the Linux SDHCI driver.
