Hmm, some clock node is broken, might be missing a name or parent
name for some reason. Can you try to boot with DEBUG enabled so you
get pr_debug:s out and see which clock is being initialized during
the crash?
...
[ 0.000000] ti_dt_clk_init_provider: ti_dt_clk_init_provider: initializing: core_d18_ck
[ 0.000000] ti_dt_clk_init_provider: ti_dt_clk_init_provider: initializing: vlynq_mux_fck
[ 0.000000] ti_dt_clk_init_provider: ti_dt_clk_init_provider: initializing: vlynq_fck
[ 0.000000] Unable to handle kernel NULL pointer dereference at virtual address 00000000

We really should be registering the clocks lazily as needed BTW. That
leaves out the dependency to DEBUG_LL for seeing any kind of decent
error messages during the booting.

Hey Tony,
Can you retry with the branch? I just pushed one patch there, seems the
parents for the vlynq_mux_fck were somewhat broken (there are holes in
the valid mux values list, which hasn't happened with any other
mux-clock so far.)
If this works, I will rework the series a bit and send v2 out.
Alternatively I need to add extra debug info.
