Thanks for checking it. Hope it's clear that
scuclk: system-controller@1fa20000
is a typo and should be
scuclk: system-controller@1fb00000
(to follow the reg property reg = <0x0 0x1fb00000 0x0 0x970>;
with the 0x970 taken from the documentation)
With this in mind and if your comment still apply do you have any hint
how to better reorganize the 2 node?
