Not sure if code that's not compiled anywhere will be accepted.

Let me directly quote Krzysztof:

"""
This a DTSI for the SoC and these clocks do not exist on the SoC. So as
usual - either they are part of board, or at least you move there the
frequency to indicate that, or put them in DTSI and include from the board.

See entire thread:

If it's not used for simplefb and not used as a carveout in drm/msm
(one can do that instead of dynamic allocation), it just takes up memory.

rename to sram@86..

you can check qcs404 for reference

Subnodes are supposed to have a -pins suffix, parent nodes should end in -state.
