Brilliant. So for every clocksource read you take a conditional. > @@ -238,7 +243,7 @@ static int __init ftm_clocksource_init(unsigned long freq) > sched_clock_register(ftm_read_sched_clock, 16, freq / (1 << priv->ps)); > err = clocksource_mmio_init(priv->clksrc_base + FTM_CNT, "fsl-ftm", > freq / (1 << priv->ps), 300, 16, > - clocksource_mmio_readl_up); > + ftm_clocksource_read_up); What's wrong with having endianess aware clocksource_mmio functions and make the decision at init time?
