Exynos 3830 Usb Driver Work [ Recommended ]

static int exynos3830_usb_disconnect(struct platform_device *pdev) { struct exynos3830_usb_phy *usb_phy;

static int exynos3830_usb_probe(struct platform_device *pdev) { struct exynos3830_usb_phy *usb_phy; int ret;

module_platform_driver(exynos3830_usb_driver);

A very specific and technical topic!

usb_phy->phy = usb_phy_get(pdev, "exynos3830-usb-phy"); if (IS_ERR(usb_phy->phy)) { ret = PTR_ERR(usb_phy->phy); kfree(usb_phy); return ret; }

ret = usb_register_dev(pdev, &exynos3830_usb_driver); if (ret) { usb_phy_put(usb_phy->phy); kfree(usb_phy); }

platform_set_drvdata(pdev, usb_phy);

struct exynos3830_usb_phy { struct usb_phy *phy; };
