--- Note this patch still needs another patch from Wolfram to work. I send out it in this series as [PATCH 3/3] arm: mxs: disable clock-gates when setting saif-clocks
As discussed with Wolfram, that patch may still have some later work to do. However, we just send out it for testers to work first. --- arch/arm/mach-mxs/clock-mx28.c | 9 +++++++++ 1 files changed, 9 insertions(+), 0 deletions(-)
