Implement the support for STM32MP25x platforms. On this platform, a

between the RNG bus and kernel clocks as on STM32MP1x platforms and
the bus clock has to be managed on its own.

A bit of a higher-level design question -- can you use drivers/clk/
clk-bulk.c clk_bulk_*() to handle all these disparate count of clock
easily ?
Hi, I'd like to make sure that we enable the core clock before the bus
clock so that the RNG hardware block can start its internal tests while
we ungate the bus clock. It's not a strong opinion but it feels better.
Maybe this could still work if the struct clk_bulk_data {} is ordered
that way, so the bus clock are first, and the rest afterward ?
I guess you meant, the core first.
Putting the bus clock first with the updated YAML doc generates a
warning when checking the bindings. I guess what you propose is OK
then. Core clock is defined first in the device tree.
