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 missing copyright notice for the linker script to help with check_compliance.py. 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]>
Move the UVC header with all the definitions from the UVC standard to share it between USB host and device class implementation. Signed-off-by: Josuah Demangeon <[email protected]>
Add tests making sure the USB Host class APIs introduced build and run as expected. Signed-off-by: Josuah Demangeon <[email protected]>
Loop through each of the VideoStreaming and VideoControl descriptor to parse them. This is meant as a stub for the purpose of testing the class API. Signed-off-by: Josuah Demangeon <[email protected]>
Add a test to run the USB Video Class host support by using the existing Zephyr USB Video Class device support. This allows running implementing the host side from the device side. A draft implementation of UVC is added leveraging this test. Signed-off-by: Josuah Demangeon <[email protected]>
The public API file <zephyr/usb/class/usbd_uvc.h> lacked an include to <zephyr/drivers/video.h> making it fail depending on the order of the includes. Signed-off-by: Josuah Demangeon <[email protected]>
Modify the USB device int sequence to read the device descriptor only after setting a valid device address. Signed-off-by: Santhosh Charles <[email protected]>
