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 <redacted>
Taken into clk-next. Regards, Mike
