commit 96bf4b89a6ab22426ad83ef76e66c72a5a8daca0 upstream.
"wakeup-source" property describes a device which has wakeup capability
but should not force this device as a wakeup source.

clocksource: Add Low Power STM32 timers driver2020-06-18T10:19:58+00:00Benjamin Gaignardbenjamin.gaignard@linaro.org2020-06-03T12:54:38+00:00urn:sha1:48b41c5e2de6c52c90efa99cfa122a5da7a7f0cd
Implement clock event driver using low power STM32 timers.
Low power timer counters running even when CPUs are stopped.
It could be used as clock event broadcaster to wake up CPUs but not like
a clocksource because each it rise an interrupt the counter restart from 0.
Low power timers have a 16 bits counter and a prescaler which allow to
divide the clock per power of 2 to up 128 to target a 32KHz rate.
