Hi,
Once again, the question is the validity of the SH2 .config file in this case (that was attached).
I don't believe that it is valid because CONFIG_SH_DEVICE_TREE=y, which selects COMMON_CLK, and there is no followparent_recalc() in the COMMON_CLK API.
Also, while CONFIG_HAVE_CLK=y, drivers/sh/Makefile prevents that from building clk/core.c, which could provide followparent_recalc():
ifneq ($(CONFIG_COMMON_CLK),y) obj-$(CONFIG_HAVE_CLK) += clk/ endif
Hm, maybe that's where the problem is. I'll look into that more.
It would be Good if someone from the SuperH area could/would comment.
Thanks.
