In case the board detected sufficient voltage for battery boot, make sure the DCDC converter is ON and the board is not running only from linregs, otherwise an instability will be observed.

Shouldn't this be conditional?
#if defined CONFIG_MXS_ENABLE_4P2 mxs_power_enable_4p2(); #endif
Then the boards that need this power supply enable CONFIG_MXS_ENABLE_4P2 in its config file.
