This patch series add support for the NXP
RTC hardware module present on S32G2/S32G3 SoCs.

The RTC module is used to enable Suspend to RAM (STR) support.
RTC tracks clock time during system suspend.

Following is an example of Suspend to RAM trigger on
S32G2/S32G3 SoCs, using userspace tools such as rtcwake:
# rtcwake -s 2 -m mem
# rtcwake: assuming RTC uses UTC ...
# rtcwake: wakeup from "mem" using /dev/rtc0 at Wed Feb 6 06:28:36 2036
#
