4 Subject: [PATCH 02/11] MIPS: BCM63XX: add USB device clock enable delay to
5 clock code
6
7 This patch adds the required 10 micro seconds delay to the USB device
8 clock enable operation. Put this where the correct clock knowledege is,
9 which is in the clock code, and remove this delay from the bcm63xx_udc
10 gadget driver where it was before.
