But I think of_quirks should be kept and we can add right quirks. In cae of DW_MCI_QUIRK_IDMAC_DTO and DW_MCI_QUIRK_RETRY_DELAY, we can handle those with dw_mci_of_quirks although we didn't add. > static struct dw_mci_board *dw_mci_parse_dt(struct dw_mci *host) > { > struct dw_mci_board *pdata; > struct device *dev = host->dev; > struct device_node *np = dev->of_node; > const struct dw_mci_drv_data *drv_data = host->drv_data; > - int idx, ret; > + int ret; > u32 clock_frequency; > > pdata = devm_kzalloc(dev, sizeof(*pdata), GFP_KERNEL); > @@ -2264,11 +2256,6 @@ static struct dw_mci_board *dw_mci_parse_dt(struct dw_mci *host) > pdata->num_slots = 1; > } > > - /* get quirks */ > - for (idx = 0; idx < ARRAY_SIZE(of_quirks); idx++) > - if (of_get_property(np, of_quirks[idx].quirk, NULL)) > - pdata->quirks |= of_quirks[idx].id; > - Same as above.
