Use dev_pm_set_wake_irq() instead of flag IRQF_NO_SUSPEND to enable wakeup system feature for both freeze(s2idle) and mem(deep). Signed-off-by: Ran Wang <ran.wang_1@nxp.com> --- Change in v2: - Remove wakeup-source control since the irq should be able to wakeup. And this is not the case that RTC interrupt line is not connected directly to SoC. drivers/rtc/rtc-fsl-ftm-alarm.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-)
