* Description:
|
|
* Board logic must provide the stm32_usbsuspend logic if the USBDEV driver
|
|
* is used. This function is called whenever the USB enters or leaves
|
|
* suspend mode. This is an oportunity for the board logic to shutdown
|
|
* clocks, power, etc. while the USB is suspended.
|
|
*
|
|
* TODO:
|
|
* - Well... implement those features like clock shutdown.
