+	* arch/arm/src/stm32/stm32_otghsdev.c: For STM32 OTG HS DEV (in FS
+	  mode): Disable ULPI clock enable in RCC AHB1 Register.  If Both ULPI
+	  and the FS clock enable bits are set in FS mode, then the ARM never
+	  awakens from WFI due to a chip issue.  This is only an issue if you
+	  are using the internal PHY.  From Ken Pettit (2012-12-13).
