[PATCH-for-9.0? v2 0/8] hw/clock: Propagate clock changes when STM32L4X5 MUX is updated

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

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 (7):
  hw/clock: Have clock_set_mul_div() return early when nothing to change
  hw/clock: Pass optional &bool argument to clock_set()
  hw/clock: Pass optional &bool argument to clock_set_ns()
  hw/clock: Pass optional &bool argument to clock_set_hz()
  hw/clock: Pass optional &bool argument to clock_set_mul_div()
  hw/misc/stm32l4x5_rcc: Inline clock_update() in clock_mux_update()
  hw/misc/zynq_slcr: Only propagate clock changes when necessary
