Subject: [MMC] Multiple cards on one host
Date: Wed, 3 Sep 2008 10:43:43 +0200 [thread overview]
Message-ID: <20080903084343.GF4941@pengutronix.de> (raw)
Hi,
I have a board (PXA based) which has two SD slots. It uses a gpio to
switch between the slots. In times when the MMC subsystem implemented
the bus topology our customer used this fact to connect the two slots on
a single host (although it was never intended to work with SD cards, it
seemed to work). Any idea how to implement this on recent kernels? I
thought about registering two hosts in pxamci.c, but this seems quite
hacky and I suppose I'll run into locking trouble.
Sascha
