kernel\msm-3.18\drivers\usb\phy\phy-msm-usb.c
motg->usb_psy.name = "usb"; motg->usb_psy.type = POWER_SUPPLY_TYPE_USB; motg->usb_psy.supplied_to = otg_pm_power_supplied_to; motg->usb_psy.num_supplicants = ARRAY_SIZE(otg_pm_power_supplied_to); motg->usb_psy.properties = otg_pm_power_props_usb; motg->usb_psy.num_properties = ARRAY_SIZE(otg_pm_power_props_usb); motg->usb_psy.get_property = otg_power_get_property_usb; motg->usb_psy.set_property = otg_power_set_property_usb; motg->usb_psy.property_is_writeable = otg_power_property_is_writeable_usb; if (!msm_otg_register_power_supply(pdev, motg)) psy = &motg->usb_psy;
kernel\msm-3.18\drivers\power\bq2570x\bq2570x_charger.c
usb_psy = power_supply_get_by_name("usb"); static int bq2570x_psy_register(struct bq2570x *bq) { int ret; bq->batt_psy.name = "dc_o2"; bq->batt_psy.type = POWER_SUPPLY_TYPE_BATTERY; bq->batt_psy.properties = bq2570x_charger_props; bq->batt_psy.num_properties = ARRAY_SIZE(bq2570x_charger_props); bq->batt_psy.get_property = bq2570x_charger_get_property; bq->batt_psy.set_property = bq2570x_charger_set_property; bq->batt_psy.external_power_changed = bq2570x_external_power_changed; bq->batt_psy.property_is_writeable = bq2570x_charger_is_writeable; ret = power_supply_register(bq->dev, &bq->batt_psy); if (ret < 0) { pr_err("failed to register batt_psy:%d\n", ret); return ret; } return 0; }
充电的闪电图标和充电动画启动逻辑
闪电图标启动逻辑:POWER_SUPPLY_TYPE_USB的power supply上报USB类型(CDP,DCP,USB)
power_supply_set_supply_type(bq->usb_psy, POWER_SUPPLY_TYPE_USB); ret = power_supply_set_online(bq->usb_psy, true); power_supply_changed(bq->usb_psy);
充电动画的启动逻辑:POWER_SUPPLY_TYPE_BATTERY的power supply上报充电状态
(CHARGE_STATE_NOT_CHARGING,CHARGE_STATE_FASTCHARGE) bq->charge_state = CHARGE_STATE_FASTCHARGE; power_supply_changed(&bq->batt_psy);
利用dumpsys分析当前battery 状态
V2_PRO:/ # dumpsys battery Current Battery Service state: AC powered: false USB powered: true Wireless powered: false Max charging current: 0 Max charging voltage: 0 Charge counter: 0 status: 2 health: 2 present: true level: 46 scale: 100 voltage: 7 temperature: 270 technology: Li-ion
