Date: Fri, 27 Nov 2009 04:36:58 +0000	[thread overview]
Message-ID: <20091127043658.13573.80166.sendpatchset@rxone.opensource.se> (raw)

From: Magnus Damm <damm@opensource.se>

This patch adds support for SDHI power control to the
Ecovec board. Platform data and power control callbacks
for SDHI0 and SDHI1 are added. Power is by default off.
