clk: shmobile: fix setting paretn clock rate
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: NBen Dooks <ben.dooks@codethink.co.uk> Acked-by: NLaurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: NMike Turquette <mturquette@linaro.org>
