is this also true for the CPU post-dividers (APB, ATB, AXI, CPU CLK TRACE)?

how are these PCIe clock related to the CPU clocks?

shouldn't all changes to this file (drivers/clk/meson/g12a.h) be part
of the patch which adds the actual clocks so the dt-bindings patch is
independent of the clock driver patches?
in this case the subject should also be updated to "dt-bindings:
clock: g12a: ..."
