From: ChiYuan Huang <cy_huang@xxxxxxxxxxx>

This patch set is to add Richtek RT9471 charger support.

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 v4:
- Remove the line for the owner field in driver.
- Add the documentation for sysfs entries.

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.
