Generally, the automotive PMICs seem to be carbon copies of their non-AU
relatives, except they're built to a better electrical spec (because well..
they're gonna be used in cars) or very very slightly modified, so I propose:
actual_pmic: pmic@sid {
compatbile = "qcom,actualpmic", "qcom,pmic-its-based-on";
}
