I tried some changes in ls1021a.dtsi file, adding RTC device in device tree and enable the freescale rtc snvs driver support in kernel.
And also checking the driver by enabling prints in rtc_snvs.c (rtc driver).
It seems like we have problem in probing, we are not getting exact register address.
Following are the dtsi file contents corresponding to freescale rtc snvs driver support.
sec_mon: sec_mon@1e90000 {
compatible = "fsl,sec-v4.0-mon","simple-bus";
#address-cells = <1>;
#size_cells = <1>;
ranges = <0x0 0x0 0x1e90000 0x10000>;
snvs_rtc: snvs_rtc_lp@34 {
compatible = "VVDN";
reg = <0x34 0x58>;
interrupts = <GIC_SPI 110 IRQ_TYPE_LEVEL_HIGH>, <GIC_SPI 111 IRQ_TYPE_LEVEL_HIGH>;
};
};
now the logs are.-

please suggest something on this issue.
