Subject: MMC: s3cmci: wirte get_cd host ops
Date: Mon, 11 Aug 2008 23:42:00 +0100 [thread overview]
Message-ID: <20080811224200.522806334@fluff.org.uk> (raw)
[-- Attachment #1: simtec/simtec-mmc-fix-card-detect.patch --]
[-- Type: text/plain, Size: 1492 bytes --]
Attach the routine to get_cd to allow the MMC core to find out whether
there is a card present or not without the tedious process of trying to
send commands to the card or not.
