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 Acked-by: Laurent Pinchart Signed-off-by: Mike Turquette --- diff --git a/drivers/clk/shmobile/clk-mstp.c b/drivers/clk/shmobile/clk-mstp.c index 42d5912b1d25..2e5810c88d11 100644 --- a/drivers/clk/shmobile/clk-mstp.c +++ b/drivers/clk/shmobile/clk-mstp.c @@ -137,7 +137,7 @@ cpg_mstp_clock_register(const char *name, const char *parent_name, init.name = name; init.ops = &cpg_mstp_clock_ops; - init.flags = CLK_IS_BASIC; + init.flags = CLK_IS_BASIC | CLK_SET_RATE_PARENT; init.parent_names = &parent_name; init.num_parents = 1;
