We gathered existing patches, fixed and improved what we could and final result is an working charging driver with device-tree support for Nexus 7. At this moment charging works with: - Nexus 7 2012 (grouper and tilapia) - Nexus 7 2013 (flo and deb) - ... and there are more devices equipped with these chargers. Changelog: v3: - The uint32 type now isn't specified for standard units in the SMB DT binding because standard units already have a type. Thanks to Rob Herring for the suggestion! - The battery binding changes are rebased on top of the new battery.yaml - The new battery temperature DT properties now have shorter names and use <min max> format. Thanks to Rob Herring for the suggestion! - Added new patch that adds SMB charger node to the new Nexus 7 2012 device-tree which has been merged into v5.9 kernel. v2: - Addressed v1 review comments from Rob Herring and Sebastian Reichel by moving out common battery properties from the charger node into the battery-cell node. - power_supply_register() of the SMB driver converted to resource-managed API variant. - Improved DT property names of the SMB binding by making them to follow the generic power-supply naming scheme (-microvolts at the end, etc).
