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 Signed-off-by: Mike Turquette (cherry picked from commit e44df332f30bf3040c60c1ed6674d1431fdb48b9) Signed-off-by: Simon Horman --- drivers/clk/shmobile/clk-mstp.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/clk/shmobile/clk-mstp.c b/drivers/clk/shmobile/clk-mstp.c index 42d5912..2e5810c 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;
