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. Regards, Tony
