SMI sub common only have one output port. thus it has only one gals clocks(gals0). then, smi-sub-common require the three clocks(apb/smi/gals0) in has_gals case. Signed-off-by: Yong Wu <yong.wu@mediatek.com> --- drivers/memory/mtk-smi.c | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-)
