Subject: [PATCH-for-9.0 v3 0/3] hw/clock: Propagate clock changes when STM32L4X5 MUX is updated
Date: Mon, 25 Mar 2024 16:28:23 +0100 [thread overview]
Message-ID: <20240325152827.73817-1-philmd@linaro.org> (raw)
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
