Due to USB controllers may have different restrictions, usb gadget layer needs to provide a generic way to inform gadget functions to complain with non-standard requirements. This patch adds 'quirk_ep_out_aligned_size' field to struct usb_gadget to inform when controller's epout requires buffer size to be aligned to MaxPacketSize. A helper is also provided to align buffer size when necessary.

If there are setup requests not directed to an endpont or an interface, current config's setup() has been attempted so far. This patch, in case the above fails, adds code which tries the setup() of configuration's function if there is only one function in the configuration. This behavior is required to provide equivalent of gadget zero with configfs. The gadget zero has a "config driver" for sourcesink, but all it does is delegating the request to the function proper. So when the equivalent gadget is set up with configfs it needs to handle requests directed to "config driver", but with configfs it is not possible to specify "config drivers".

The dsps platform needs to save save some registers at suspend time and restore them after resume. This patch adds a struct for these registers, and also lets the musb core know that the core registers need to be saved as well. We also have to explicitly de-assert the port reset upon resume on this platform, but musb_port_reset() should not be called from glue layers. Hence, introduce a flag in struct musb_hdrc_config for this. Signed-off-by: NDaniel Mack <zonque@gmail.com> Signed-off-by: NFelipe Balbi <balbi@ti.com>
