Thanks for the feedback.
I think that the issue is bacause clk_get() on fck_source is failing as TI816X
clock data had different clock source names compared to OMAP3 (e.g., osc_sys_ck
instead of sys_ck). I will update this in next version.
Even after this, the kernel would get stuck at "Calibrating delay loop..."
because a few timer register offsets on TI81XX are different than OMAP3. I see
there are some patches floating on ML which add reg_map array (similar to i2c
driver) but seems they have not (yet) been accepted. Any chance that this will
get added to kernel?
