Add a "struct usbh_status" that contains a bitmask of flags to keep track of the global state of the host context, like done for the device_next implementation. Signed-off-by: Josuah Demangeon <[email protected]>
Add a "struct usbh_class_api" for the host implementation, and move all the function poitners to it. Add more fields to "struct usbh_class_data". Signed-off-by: Josuah Demangeon <[email protected]>
Add API wrappers around the function pointers in struct usbh_class_api, while also documenting the USB host class internal API. Signed-off-by: Josuah Demangeon <[email protected]>
Add functions to probe/remove all classes as part of a new usbh_class.c and a matching usbh_class.h. These functions are called from the function usbh_init_device_intl() in usbh_core.c to initialize every class upon connection of a device. Every class driver provide filters to match the interfaces of the device. Co-authored-by: Aiden Hu <[email protected]> Signed-off-by: Josuah Demangeon <[email protected]>
Allocate extra room at the end of the USB descriptor buffer to ensure that the device ends with `desc->bLength == 0`. For now, validating `desc->bLength` from the device to ensure no access past the buffer is still not done. Signed-off-by: Josuah Demangeon <[email protected]>
Introduce subsys/usb/common as a new directory intended to hold sources and configuration that are shared between USB host and device implementations. Integrate the new common directory into the build system. Signed-off-by: Santhosh Charles <[email protected]> Signed-off-by: Josuah Demangeon <[email protected]>
