Hi,

My guess (analysis) suggests that this problem is due to a difference in when clk_get_parent() is available between <linux/clk.h> where it depends on CONFIG_HAVE_CLK and drivers/clk/clk.c, which is built iff CONFIG_COMMON_CLK.

Any comments/suggestions?

thanks.

The .config would help to reproduce this.
I don't see it attached.
