Steps to reproduce
With sleep manager introduced, deep sleep will be locked (sleep_manager_lock_deep_sleep) as Timer is started. LowPowerTimer inherits Timer and so use of it will also lock deep sleep. As I know, LowPowerTimer (and LowPowerTicker/LowPowerTimeout) rely on lp_ticker and would still work even though system enters deep sleep mode. They shouldn't lock deep sleep.
#include "mbed.h"
int main()
{
static LowPowerTimer timer;
timer.start();
while (true) {
deepsleep();
}
return 0;
}
