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.
