-Subject: [PATCH 02/11] MIPS: BCM63XX: add USB device clock enable delay to
- clock code
-
-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.
