From be9cd7b6f84fd0cc59c8770771073b5c66f958ac Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Fri, 27 Nov 2009 04:31:27 +0000 Subject: [PATCH] mfd: Add power control platform data to SDHI driver This patch adds platform data with a function for power control to the SDHI driver. The idea is that board specific code can provide their own functions so power can be enabled and disabled for the sd-cards.
