usb: gadget: zero: Add support for interrupt EP
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. Signed-off-by: Amit Virdi <amit.virdi@st.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
