The code in pinctrl-imx.c only works correctly if in the imx_pinctrl_soc_info passed to imx_pinctrl_probe we have: info->pins[i].number = i conf_reg(info->pins[i]) = 4 * i (which conf_reg(pin) being the offset of the pin's configuration register). When the imx25 specific part was introduced inb4a87c9b96
("pinctrl: pinctrl-imx: add imx25 pinctrl driver") we had: info->pins[i].number = i + 1 conf_reg(info->pins[i]) = 4 * i . Commit34027ca2bb
("pinctrl: imx25: fix numbering for pins") tried to fix that but made the situation: info->pins[i-1].number = i conf_reg(info->pins[i-1]) = 4 * i which is hardly better but fixed the error seen back then. So insert another reserved entry in the array to finally yield: info->pins[i].number = i conf_reg(info->pins[i]) = 4 * i Fixes:34027ca2bb
