However, The regulator information is based on an older temporary pre-production board variant and does not reflect production board 750-2628-XXX boards - On production boards, LDO2 and 8 are unused. LDO2 and LDO8 do not go to any peripheral or connector on the board. Further, these unused regulators should have been 2.8V for LDO2 and 3.0V for LDO8. Mark these LDOs as disabled in the dts until needed.
