Correct ldo1 voltage range from wrong high group(3.0v~3.3v) to low group (1.6v~1.9v) because the ldo1 should be 1.8v. Actually, two voltage groups have been supported at bd718x7-regulator driver, hence, just corrrect the voltage range to 1.6v~3.3v. For [email protected], correct voltage range too. Otherwise, ldo1 would be kept @3.0v and [email protected] which violate i.mx8mm datasheet as the below warning log in kernel:
