From fdb9de129e1d68e1b804bc9c8b3027bea9b88bc8 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Tue, 13 Jan 2015 08:23:18 +1300 Subject: [PATCH] mmc: omap_hsmmc: use mmc_of_parse to parse common mmc configuration. This ensures that all standard options are available to hsmmc, In particular, I need cap-power-off-card.
