stm32l4_otgfs: enable OTGFS for STM32L4+ series The OTGFS peripheral on stm32l4x6 and stm32l4rxxx reference manual is exactly the same. This patch also adds missing bits and fixes errors in stm32l4x5xx and stm32l4x6xx OTGFS register maps. Approved-by: Gregory Nutt <gnutt@nuttx.org>

* Name: stm32l4_otgfshost_initialize
|
|
*
|
|
* Description:
|
|
* Initialize USB host device controller hardware.
|
|
*
|
|
* Input Parameters:
|
|
* controller -- If the device supports more than USB host controller, then
|
|
* this identifies which controller is being initialized. Normally, this
|
|
* is just zero.
|
|
*
|
|
* Returned Value:
|
|
* And instance of the USB host interface. The controlling task should
|
|
* use this interface to (1) call the wait() method to wait for a device
|
|
* to be connected, and (2) call the enumerate() method to bind the device
|
|
* to a class driver.
|
|
*
|
|
* Assumptions:
|
|
* - This function should called in the initialization sequence in order
|
|
* to initialize the USB device functionality.
|
|
* - Class drivers should be initialized prior to calling this function.
|
|
* Otherwise, there is a race condition if the device is already connected.
