usb: gadget: Introduce handle_interrupts ops to USB_GADGET_GENERIC uclass 2024-07-05T12:06:05+00:00 Marek Vasut marek.vasut+renesas@mailbox.org 2024-06-14T00:51:16+00:00 d36ef5cbedd08e9a11c6a719d853f1003173133e Introduce .ops for USB_GADGET_GENERIC uclass. The first new ops is .handle_interrupts which must be implemented by DM capable USB gadget controller drivers and must implement interrupt handling similar to dm_usb_gadget_handle_interrupts(). This patch currently provides weak dm_usb_gadget_handle_interrupts() implementation which is overridden by the drivers, but this will be removed once conversion to handle_interrupts callback is complete.
