Hi All,


I am using a custom board with IMX6ULL processor. I wanted to keep date and time running in sleep mode, for that we need to use snvs rtc. I am keeping processor in sleep by "echo mem > /sys/power/state" command. When we see BSP for snvs rtc (rtc-snvs.c) it seems, it is trying to read from SNVS_LPSRTCMR and SNVS_LPSRTCLR register which is not present in IMX6ULL, instead it is present in IMX6UL. Can any one help me out on how to use snvs rtc for IMX6ULL?
