SMDK5250: Enable VBus for USB 2.0 controller
PATCH v4 1/1 SMDK5250: Enable VBus for USB 2.0 controller
This patch enables Vbus required for USB 2.0 controller.
---
Changes from v3:
- Rebased on top of u-boot-samsung/master.
Changes from v2:
- Rebased on top of u-boot-usb/next
- Enclosed the function definition for board_usb_vbus_init() inside "CONFIG_USB_EHCI_EXYNOS"
Changes from v1:
- Using the old school method of setting up gpio instead of using the pinmux method, since the required gpio line here is board specific.
