+* ROHM BD70528 Power Management Integrated Circuit bindings
+
+BD70528MWV is an ultra-low quiescent current general purpose, single-chip,
+power management IC for battery-powered portable devices. The IC
+integrates 3 ultra-low current consumption buck converters, 3 LDOs and 2
+LED Drivers. Also included are 4 GPIOs, a real-time clock (RTC), a 32kHz
+clock gate, high-accuracy VREF for use with an external ADC, flexible
+dual-input power path, 10 bit SAR ADC for battery temperature monitor and
+1S battery charger with scalable charge currents.
