| |
Even though the ChipIdea USB controller binding[1] doesn't specify the properties that reference a PHY as required, the Linux driver requires[2] such a reference.
The clock situation is like on i.MX53: The USB controller is clocked from IMX5_CLK_USBOH3_GATE and the PHY from IMX5_CLK_USB_PHY1_GATE.
