The RT9471/D is a highly-integrated 3A switch mode battery charge management and system power path management device for single cell Li-Ion and Li-polymer battery. The low impedance power path optimizes switch-mode operation efficiency, reduces battery charging time and extends battery life during discharging phase. Since v3: - Move unevaluatedProperties line after $ref for binding patch. - Add Reviewed-by tag for binding patch. Since v2: - Remove the properties for interrupt controller things in the binding documentation. - Fix dtc error for typo, it's 'regulator-name', not 'regulator-compatible'. - Add regulator min/max microamp to allow otg vbus current adjustable in example. - Specify the active-level for charge-enable-gpios in binding example. - Fix checkpatch error about 'foo * bar' to 'foo *bar' in psy_device_to_chip function. - Specify the member name directly for the use of linear range.
