Since you are here, you may also want to remove the "if (np)" check for non-dt probe case getting devid and dma_channel. As the result, mxs_ssp_ids can be removed as well. It could be another patch though, so for this one: Acked-by: Shawn Guo <[email protected]> > + of_property_read_u32(np, "bus-width", &bus_width); > + if (bus_width == 4) > + mmc->caps |= MMC_CAP_4_BIT_DATA; > + else if (bus_width == 8) > + mmc->caps |= MMC_CAP_4_BIT_DATA | MMC_CAP_8_BIT_DATA; > + host->wp_gpio = of_get_named_gpio_flags(np, "wp-gpios", 0, &flags); > + > + if (flags & OF_GPIO_ACTIVE_LOW) > + host->wp_inverted = 1; > > mmc->f_min = 400000; > mmc->f_max = 288000000; > diff --git a/include/linux/mmc/mxs-mmc.h b/include/linux/mmc/mxs-mmc.h > deleted file mode 100644 > index 7c2ad3a..0000000 > -- > 1.7.9.5 > -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
