--- Changes since v4: * Using the new added master_id and master_mode in platfrom_data No changes since v3: Changes since v2: * separate clkmux code into another patch * A few minus fixes suggested by Uwe & Wolfram. Changes since v1: * move saif clkmux code into mach-specific part --- arch/arm/mach-mxs/devices-mx28.h | 3 ++- arch/arm/mach-mxs/devices/platform-mxs-saif.c | 5 +++-- arch/arm/mach-mxs/include/mach/devices-common.h | 4 +++- arch/arm/mach-mxs/mach-mx28evk.c | 18 ++++++++++++++++-- 4 files changed, 24 insertions(+), 6 deletions(-)
