NACK. You're not specifying the L2 cache correctly.
Hint: the missing properties are
cache-size
cache-line-size
cache-sets

Same here. Please properly define the L2 cache.

And again.
This SoC has 256KB L2 shared between the two A78 cores, 128KB L2 shared
between the A55 cores, and 2MB of L3 cache shared across all.
