Hey,

When I boot my A83T I get the following bootlog [1].

After some debugging, I found out that the function call:
clk_hw_get_num_parents() returns 2. After a look in the devicetree I
found out that this value should be 1, since we only have one parent
clock [3].
Setting the variable num_parents to 1 fixes the problem, but this is no
soultion.

Regards,
Philipp
