Subject: [RESEND 0/4] Fix issue when using devm_of_regulator_put_matches and add compatiblity for both fixed and adjustable LDO VOUT

Hi,

There are two types of LDO VOUT: fixed voltage mode and adjustable voltage mode.

As the fixed voltage for the LDO is outside the range of the adjustable voltage mode,
the constraints for this scenario are not suitable to represent both modes.
Therefore, A property is added to specify the fixed LDO VOUT.

In this version, a software bug has been fixed.
rtq2208_ldo_match is no longer a local variable.
It prevents invalid memory access when devm_of_regulator_put_matches is called.

Alina Yu (4):
  regulator: rtq2208: Fix invalid memory access when
    devm_of_regulator_put_matches is called
  regulator: rtq2208: Fix LDO to be compatible with both fixed and
    adjustable vout
  regulator: rtq2208: Add fixed LDO VOUT property and check that matches
    the constraints
  regulator: dt-bindings: rtq2208: Add specified fixed LDO VOUT property
