I believe that this series is ready for merging now. Since patches 14-20 rely on the power-supply changes from patch 1-13 and since they all touch files which generally do not see much changes, the intention is for this entire series to be merged through your (Sebastian's) linux-power-supply tree. Patches 14-20 all have acks from the relevant subsystem maintainers for merging them through the linux-power-supply tree. ### For more details on this series, here is some info from the v2 cover-letter: So far almost all the kernel code surrounding the Cherry Trail Whiskey Cove PMIC has been developed on the GPD win / pocket devices and it has various assumption based on that. In the mean time I've learned (and gotten access to) about 2 more designs and none of the 3 now known designs use a single standard setup for the charger, fuel-gauge and other chips surrounding the PMIC / charging+data USB port: 1. The GPD Win and GPD Pocket mini-laptops, these are really 2 models but the Pocket re-uses the GPD Win's design in a different housing: The WC PMIC is connected to a TI BQ24292i charger, paired with a Maxim MAX17047 fuelgauge + a FUSB302 USB Type-C Controller + a PI3USB30532 USB switch, for a fully functional Type-C port. 2. The Xiaomi Mi Pad 2: The WC PMIC is connected to a TI BQ25890 charger, paired with a TI BQ27520 fuelgauge, using the TI BQ25890 for BC1.2 charger type detection, for a USB-2 only Type-C port without PD. 3. The Lenovo Yoga Book YB1-X90 / Lenovo Yoga Book YB1-X91 series: The WC PMIC is connected to a TI BQ25892 charger, paired with a TI BQ27542 fuelgauge, using the WC PMIC for BC1.2 charger type detection and using the BQ25892's Mediatek Pump Express+ (1.0) Unlike what is normal on X86 this diversity in designs is not handled / abstracted away by the ACPI tables. This series takes care of making sure that charging and device/host mode switching also works on the Xiaomi Mi Pad 2 and the Lenovo Yogabook. Patches 1-13: Prepare the bq25890 power_supply driver to fully support the Mi Pad 2 and the Yogabook. Note this includes a new version of 2 bq25890 patches send earlier by Yauhen Kharuzhy Patch 14: Adds the intel_cht_wc_get_model() helper Patch 15: Uses this intel_cht_wc_get_model() value to instantiate an i2c-client with the right type and properties for the charger IC used on the board (instead of harcoding the GPD values) Patches 16-20: Modify the extcon code to provide charger-detection results to the charger driver and to take care of the Vbus boost regulator control (for host-mode) and device/host mode switching I've tried to keep the power_supply patches as generic as possible while focussing some of the special handling these boards need in the WC PMIC MFD and cell drivers, which will only get loaded on these boards. Regards, Hans p.s.
