From: Linus Walleij Date: Wed, 30 Mar 2011 14:00:39 +0000 (+0200) Subject: mach-ux500: correct MMC/SDI parameters X-Git-Tag: firefly_0821_release~3680^2~4841^2~1^7~14 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=02a734373b998efdcb9d28d8c3aa77e549bb38c0;p=firefly-linux-kernel-4.4.55.git mach-ux500: correct MMC/SDI parameters We cannot clock the MMCI blocks more than 50 MHz. A bug prevented us from seeing the effect of actually driving them to 100 MHz, which indeed resulted failure, on the external SD card.
