The A83T's PRCM has the same set of clocks and resets as the A64. However, a few dividers are different. And due to the lack of a low speed 32.768 kHz oscillator, a few of the clock parents are different. The PRCM also has controls for various power domains. These are not supported yet, neither in software nor in the device tree binding.

I applied patches 1 and 2, but that made me realise that the pll-periph0 is also a parent and should be listed there. Can you send a patch adjusting the binding documentation so that we can have it in time for 4.12, and patches for the A64 / H3 DTSs ?
