From: Marek Vasut Date: Sun, 17 Mar 2024 04:42:52 +0000 (+0100) Subject: usb: udc: dwc3: Fold board dm_usb_gadget_handle_interrupts() into DWC3 gadget X-Git-Url: http://git.dujemihanovic.xyz/html/%7B%7B%20%28.OutputFormats.Get?a=commitdiff_plain;h=4d158980897085a5b0255ab910208d8afc8522dc;p=u-boot.git usb: udc: dwc3: Fold board dm_usb_gadget_handle_interrupts() into DWC3 gadget The dm_usb_gadget_handle_interrupts() has no place in board code. Move this into DWC3 driver. The OMAP implementation is special, add new weak dwc3_uboot_interrupt_status() function to decide whether DWC3 interrupt handling should be called, and override it in OMAP DWC3 code, to repair the special OMAP interrupt handling code until OMAP gets switched over to DM UDC proper.
