From 544f277bb849da0ba86cfc4203a4c9139e2cd927 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Thu, 4 Jun 2009 20:12:35 +0200 Subject: [PATCH] tmio_mmc: map SD control registers after enabling the MFD cell ASIC3 can disable the memory, so we need to wait for mfd_cell->enable to enable the memory before we can map the SD control registers.
