Example #1

void imx233_digctl_set_arm_cache_timings(unsigned timings)
{
#if IMX233_SUBTARGET >= 3780
    BF_WR_ALL(DIGCTL_ARMCACHE, ITAG_SS(timings),
        DTAG_SS(timings), CACHE_SS(timings), DRTY_SS(timings), VALID_SS(timings));
#else
    BF_WR_ALL(DIGCTL_ARMCACHE, ITAG_SS(timings),
        DTAG_SS(timings), CACHE_SS(timings));
#endif
}

Example #2

void imx233_chip_reset(void)
{
#if IMX233_SUBTARGET >= 3700
    HW_CLKCTRL_RESET = BM_CLKCTRL_RESET_CHIP;
#else
    BF_WR_ALL(POWER_RESET, UNLOCK_V(KEY), RST_DIG(1));
#endif
}
