Subject: [PATCH 23/93] drivers: usb: fsl: add USB ULPI init code
|
||
|
|
|
||
|
|
This adds the required code to set up a ULPI USB port, for
|
||
|
|
new NXP USB PHY used in QorIQ platforms.
|
||
|
|
|
||
|
|
To use this both CONFIG_USB_ULPI and CONFIG_USB_ULPI_VIEWPORT
|
||
|
|
have to be set in the board configuration file.
|
||
|
