Since maxpacket_limit was introduced all UDC drivers should use usb_ep_set_maxpacket_limit() function instead of setting maxpacket value manually. ep.maxpacket_limit contains actual maximum maxpacket value supported by hardware which is needed by epautoconf. Signed-off-by:

Function midi registers two interfaces with single set_alt() function which means that f_midi_set_alt() is called twice when configuration is set. That means that endpoint initialization and ep request allocation is done two times. To avoid this problem we do such things only once, for interface number 1 (MIDI Streaming interface).

Function ffs_do_functionfs_bind() calls functionfs_bind() which allocates usb request and increments refcounts. These things needs to be cleaned up by if further steps of initialization fail by calling functionfs_unbind(). Signed-off-by:

According to USB Audio Device 2.0 Spec, Ch4.10.1.1: wMaxPacketSize is defined as follows: Maximum packet size this endpoint is capable of sending or receiving when this configuration is selected. This is determined by the audio bandwidth constraints of the endpoint. In current code, the wMaxPacketSize is defined as the maximum packet size for ISO endpoint, and it will let the host reserve much more space than it really needs, so that we can't let more endpoints work together at one frame. We find this issue when we try to let 4 f_uac2 gadgets work together [1] at FS connection. [1]http://www.spinics.net/lists/linux-usb/msg123478.htmlAcked-by:

Robert Baldyga authored
Due to some UDC controllers may not support zlp, usb gadget layer needs to provide a generic way to inform gadget functions about non-standard hardware limitations. This patch adds 'quirk_zlp_not_supp' field to struct usb_gadget and helper function gadget_is_zlp_supported(). It also sets 'quirk_zlp_not_supp' to 1 in musb UDC driver, which has such limitation.

Use chained TRB mechanism to handle non maxpacket aligned transfers greater than bounce buffer size. With this the first TRB will be programmed to receive 'ALIGN(ur->length - maxp, maxp)' data and the second TRB will be programmed to receive the remaining data using bounce buffer. Signed-off-by:

No functional change. Added a new parameter in _dwc3_ep0_start_trans_ to indicate whether the TRB is a chained TRB or last TRB. This is in preparation for adding chained TRB support for ep0. Signed-off-by:

No functional change. This is in preparation for handling non maxpacket aligned transfers greater than bounce buffer size. This is basically to avoid code duplication when using chained TRB transfers to handle non maxpacket aligned transfers greater than bounce buffer size. Signed-off-by:

No functional change. Used _roundup_ macro to calculate the transfer size aligned to maxpacket in dwc3_ep0_complete_data. It also makes it similar to how transfer size is calculated in __dwc3_ep0_do_control_data. Signed-off-by:

DWC3 uses bounce buffer to handle non max packet aligned OUT transfers and the size of bounce buffer is 512 bytes. However if the host initiates OUT transfers of size more than 512 bytes (and non max packet aligned), the driver throws a WARN dump but still programs the TRB to receive more than 512 bytes. This will cause bounce buffer to overflow and corrupt the adjacent memory locations which can be fatal. Fix it by programming the TRB to receive a maximum of DWC3_EP0_BOUNCE_SIZE (512) bytes.
