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.
