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 v6: - Use 'ATTRIBUTE_GROUPS' macro to simplify the attribute coding. - Explain more details for sysoff_enable attribute. Since v5: - Remove one line wrapper. - Merge header content into source file, remove header file. - Remove 'charge_term_enable' sysfs entry and merge it into 'charge_term_current' property control. - Change MODULE_LICENSE from 'GPL v2' to 'GPL'. Following by the below discussion https://lore.kernel.org/all/YxAVAt2eWB3NFlrk@xxxxxxxxxx/ - Recover all the change in sysfs-class-power. - New a sysfs-class-power-rt9471 file. - Remove 'charge_term_enable' sysfs entry, directly integrate it in 'charge_term_current' power supply property control. 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.
