12description:
13  The PF0900 is a power management integrated circuit (PMIC) optimized
14  for high performance i.MX9x based applications. It features five high
15  efficiency buck converters, three linear and one vaon regulators. It
16  provides low quiescent current in Standby and low power off Modes.
