From: Guy Shapiro <guy.shapiro@xxxxxxxxxxxxx> Make the syscon-poweroff driver change only the shutdown bits on the SNVS_LP control register. This change fixes an issue with the RTC wakeup alarm, that was previously disabled during power off. Signed-off-by: Guy Shapiro <guy.shapiro@xxxxxxxxxxxxx> Reviewed-by: Marcin Niestroj <m.niestroj@xxxxxxxxxxxxxxxx> --- Hi, This is a resend of second patch from patch series [1]. First patch is already in v4.12, but this one was not applied. Tested on imx6ul board. Without that patch RTC time is "frozen" during power-down state. With that patch RTC shows proper time after exiting from power-down.
