It was just strange for me to see the regulators being set-up in the charger driver. I would have expected to see separate regulator driver for this, I guess this is MFD in any case, right? So I would have expected seeing a sub-device for regulators. I however see we have couple of other charger drivers here doing the same thing (setting up regulators in charger driver) - so if this is normal then I for sure have no objections :) > > ... > > > > > +static int mt6360_charger_probe(struct platform_device *pdev) > > > +{ > > > + struct mt6360_chg_info *mci; > > > + struct power_supply_config charger_cfg = {}; > > > + struct regulator_config config = { }; > > > + int ret; > > > + > > > + mci = devm_kzalloc(&pdev->dev, sizeof(*mci), GFP_KERNEL); > > > + if (!mci) > > > + return -ENOMEM; > > > + > > > + ret = mt6360_parse_dt(pdev); > > > + if (ret) > > > + return dev_err_probe(&pdev->dev, ret, "Failed to > > > parse > > > dt\n"); > > > + > > > + mci->dev = &pdev->dev; > > > + mci->vinovp = 6500000; > > > + mutex_init(&mci->chgdet_lock); > > > + platform_set_drvdata(pdev, mci); > > > + INIT_WORK(&mci->chrdet_work, &mt6360_chrdet_work); > > > + > > > + mci->regmap = dev_get_regmap(pdev->dev.parent, NULL); > > > + if (!mci->regmap) > > > + return dev_err_probe(&pdev->dev, -ENODEV, "Failed > > > to > > > get parent regmap\n"); > > > + > > > + ret = mt6360_apply_dt(pdev); > > > + if (ret) > > > + return dev_err_probe(&pdev->dev, ret, "Failed to > > > apply > > > dt\n"); > > > + > > > + memcpy(&mci->psy_desc, &mt6360_charger_desc, sizeof(mci- > > > > psy_desc)); > > > + mci->psy_desc.name = dev_name(&pdev->dev); > > > + charger_cfg.drv_data = mci; > > > + charger_cfg.of_node = pdev->dev.of_node; > > > + mci->psy = devm_power_supply_register(&pdev->dev, > > > + &mci->psy_desc, > > > &charger_cfg); > > > + if (IS_ERR(mci->psy)) > > > + return dev_err_probe(&pdev->dev, PTR_ERR(mci->psy), > > > + "Failed to register power > > > supply > > > dev\n"); > > > + > > > + ret = mt6360_chg_init_setting(mci); > > > + if (ret) > > > + return dev_err_probe(&pdev->dev, ret, "Failed to > > > initial setting\n"); > > > + > > > + schedule_work(&mci->chrdet_work); > > > > Is this work scheduled anywhere else?

I was just wondering why not checking charger status right here? I didn't understand why the checking was pushed to a WQ. You probably have a valid reason. I assume it's just me who is not understanding this :) Additionally I was wondering what happens if for example the IRQ registration below fails and we detach the driver - I don't see work-queue being flushed.
