If the driver needs to change a clock rate, then it must be propogated through the MSTP clock to the parent clock (such as shdi0 -> sd0). Without this we cannot up-rate default clocks which are really slow (such as the mmcif1 which defaults to 12MHz where it could be running at 97MHz) Signed-off-by: Ben Dooks <ben.dooks@codethink.co.uk> --- drivers/clk/shmobile/clk-mstp.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
