Since v2:
- Simpler approach

Since v1:
- Rework API to only propagate when both clock_set
  and clock_set_mul_div modified the clock params
  (Peter & Luc).
- Use that in zynq_slcr.

Per https://www.qemu.org/docs/master/devel/clocks.html#clock-multiplier-and-divider-settings:

  Note that clock_set_mul_div() does not automatically call
  clock_propagate(). If you make a runtime change to the
  multiplier or divider you must call clock_propagate() yourself.

Fix what we forgot to do that in recent commit ec7d83acbd
("hw/misc/stm32l4x5_rcc: Add an internal clock multiplexer object")

Arnaud Minier (1):
  hw/misc/stm32l4x5_rcc: Propagate period when enabling a clock

Philippe Mathieu-Daudé (2):
  hw/clock: Let clock_set_mul_div() return a boolean value
  hw/misc/stm32l4x5_rcc: Inline clock_update() in clock_mux_update()
