Subject: [PATCH 1/4] mci: rename capabilities flags
Date: Mon,  3 Jun 2013 12:49:37 +0200	[thread overview]
Message-ID: <1370256580-3113-1-git-send-email-s.hauer@pengutronix.de> (raw)

Use MMC_CAP_ names instead of MMC_MODE_. This makes it more
clear that these are capabilities of host/card and do not refer
to the current mode. These are in line with the Linux Kernel
except for MMC_CAP_MMC_HIGHSPEED_52MHZ which could be fixed
later.
