--- v4: similar to Nitrogen6x: add otg usb ethernet gadget support But I added pad setup for over current, otg_id, and power control Added board_ehci_power function to enable power for host mode. Removed otg_id selection done now in previous patch.
v5: changed MX6_PAD_GPIO_1__USBOTG_ID to MX6_PAD_GPIO_1__USB_OTG_ID. --- board/boundary/nitrogen6x/nitrogen6x.c | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+)
