Here is how they look.

static int __init mxs_arch_reset_init(void)
{
        struct clk *clk;

        wdog_base = cpu_is_mx23() ? MX23_IO_ADDRESS(MX23_RTC_BASE_ADDR) :
                                    MX28_IO_ADDRESS(MX28_RTC_BASE_ADDR);

        clk = clk_get_sys("rtc", NULL);
        if (!IS_ERR(clk))
                clk_enable(clk);
        else

        return 0;
}
core_initcall(mxs_arch_reset_init);

static int __init mxs_iomux_init(void)
{
        iomux_base = MXS_IO_ADDRESS(MXS_PINCTRL_BASE_ADDR);

        return 0;
}
core_initcall(mxs_iomux_init);
