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.

The A31 SoC uses the same musb controller as found in earlier SoCs, but it is hooked up slightly different. Its SRAM is private and no longer controlled through the SRAM controller, and its reset is controlled via a separate reset controller. This commit adds support for this setup. Signed-off-by:

This is based on initial code to get the Allwinner sunxi musb controller supported by Chen-Yu Tsai and Roman Byshko. This adds support for the Allwinner sunxi musb controller in both host only and otg mode. Peripheral only mode is not supported, as no boards use that. This has been tested on a cubietruck (A20 SoC) and an UTOO P66 tablet (A13 SoC) with a variety of devices in host mode and with the g_serial gadget driver in peripheral mode, plugging otg / host cables in/out a lot of times in all possible imaginable plug orders.

Use bind_deactivated flag instead of calling usb_function_deactivate() in function bind(). Field 'can_activate' in struct f_obex is no longer needed as setting 'bind_deactivated' flag makes us sure, that the function will be binded only if deactivation can be performed successfully. Signed-off-by:

This patch introduces 'bind_deactivated' flag in struct usb_function. Functions which don't want to be activated automatically after bind should set this flag, and when they start to be ready to work they should call usb_function_activate(). When USB function sets 'bind_deactivated' flag, initial deactivation counter is incremented automatically, so there is no need to call usb_function_deactivate() in function bind. Signed-off-by:

Using usb_gadget_disconnect to make gadget temporarily invisible to host doesn't provide desired result, because gadget is connected immediately after binding regardless to previous usb_gadget_disconnect() calls. For this reason we use usb_gadget_deactivate() instead of usb_gadget_disconnect() to make it working as expected. Signed-off-by:

These functions allows to deactivate gadget to make it not visible to host and make it active again when gadget driver is finally ready. They are needed to fix usb_function_activate() and usb_function_deactivate() functions which currently are not working as usb_gadget_connect() is called immediately after function bind regardless to previous calls of usb_gadget_disconnect() function.
