I'm trying to set the SNVS_TAMPER2 pin as follows:

&iomuxc_snvs {
    pinctrl-names = "default_snvs";
    pinctrl-0 = <&pinctrl_hog_2>;
    imx6ull-evk {
    pinctrl_hog_2: hoggrp-2 {
        fsl,pins = <
            MX6ULL_PAD_SNVS_TAMPER2__GPIO5_IO02    0x17059


but when I try to read the register of the pin I find the following value:


~# devmem2 0x2290054
/dev/mem opened.
Memory mapped at address 0x76f8c000.
Read at address  0x02290054 (0x76f8c054): 0x000110A0


what's the problem?


Thanks so much
