    usb: gadget: zero: Add support for interrupt EP · ef11982d
    Amit Virdi authored
    Interrupt endpoints behave quite similar to the bulk endpoints with the
    difference that the endpoints expect data sending/reception request at
    particular intervals till the whole data has not been transmitted.
    
    The interrupt EP support is added to gadget zero. A new alternate setting (=2)
    has been added. It has 2 interrupt endpoints. The default parameters are set as:
    	bInterval: 1 ms for FS and 8 uFrames (implying 1 ms) for HS/SS
    	wMaxPacketSize: 64 bytes for FS and 1024 bytes for HS/SS
    However, the same can be overridden through the module parameter interface.
    
    The code is tested for HS and SS on a platform having DWC3 controller.
