[PATCH] ARM: OMAP4: clock: Initialize USB DPLL

2013-03-21 Thread Roger Quadros
If the bootloader doesn't configure USB DPLL (e.g. in u-boot, disable CONFIG_USB_EHCI_OMAP), then we get all sorts of problems like - division by zero errors at boot [1] - USB DPLL fails to enter locked state - USB EHCI Host is non functional - Device can't enter OFF mode Initializing the USB DPLL
