How to use the Secure RTC in imx8qxp?

[charleshuang]

Hi NXP Team

Our cusotmer need to use the Secure RTC in imx8qxp platform.

1. The Secure RTC is Hardware feature.   Is it support the Secure RTC in imx8qxp platform?

2.   Is it the driver support the Secure RTC (Yocto 2.5 3.0 or 3.3)?

      imx8QXP  dts  ->  imx8qxp-sc-rtc     in  kernel/drivers/rtc/rtc-imx-sc.c 

3. How to use the Secure RTC in imx8qxp?

    Do you have SOP about how to setting Secure RTC?

Thanks.
