+Subject: [PATCH 01/11] MIPS: BCM63XX: add USB host clock enable delay
+
+Knowledge of the clock setup delay should remain at the clock level (so
+it can be clock specific and CPU specific). Add the 100 milliseconds
+required clock delay for the USB host clock when it gets enabled.

+
+This patch adds the required 10 micro seconds delay to the USB device
+clock enable operation. Put this where the correct clock knowledege is,
+which is in the clock code, and remove this delay from the bcm63xx_udc
+gadget driver where it was before.
