The PMIC on Apalis iMX6 may have ECC errors in fuses that will prevent correct settings. Up to one bit error per fuse bank may be reported and corrected by the ECC logic. Two bit errors can only be reported. Signed-off-by: Gerard Salvatella <gerard.salvatella@toradex.com> Acked-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>
