From ec5499d338ece9db9b7590649d3cfcc4d7f9603d Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 31 Jan 2023 16:04:31 +0100 Subject: [PATCH] xhci: split out rcar/rz support from xhci-plat.c The USB_XHCI_RZV2M and USB_RENESAS_USB3 select other drivers based on the enabled SoC types, which leads to build failures when the dependencies are not met: WARNING: unmet direct dependencies detected for USB_RZV2M_USB3DRD Depends on [n]: USB_SUPPORT [=y] && USB_GADGET [=n] && (ARCH_R9A09G011 [=n] || COMPILE_TEST [=y]) Selected by [m]: - USB_XHCI_RZV2M [=m] && USB_SUPPORT [=y] && USB [=y] && USB_XHCI_HCD [=m] && USB_XHCI_PLATFORM [=m] && (ARCH_R9A09G011 [=n] || COMPILE_TEST [=y]) ERROR: modpost: "rzv2m_usb3drd_reset" [drivers/usb/host/xhci-plat-hcd.ko] undefined! The xhci-rcar driver has a reverse dependency with the xhci core, and it depends on the UDC driver in turn. To untangle this, make the xhci-rcar.ko driver a standalone module that just calls into the xhci-plat.ko module like other drivers do. This allows handling the dependency on the USB_RZV2M_USB3DRD driver to only affect the xhci-rcar module and simplify the xhci-plat module. It also allows leaving out the hacks for broken dma mask and nested devices from the rcar side and keep that only in the generic xhci driver. As a future cleanup, the marvell and dwc3 specific bits of xhci-plat.c could be moved out as well, but that is not required for this bugfix.
