From e327e2affd302b7fd15b655624fdacb2f0492eab Mon Sep 17 00:00:00 2001 From: Neil Armstrong Date: Tue, 17 Jan 2023 10:11:46 +0100 Subject: [PATCH] ARM: meson: switch AXG & GX dwc2 otg to DM With CONFIG_DM_USB_GADGET=y, we no longer need any board_usb_*() logic because: * the dwc2 driver is DM compatible, and handles its own clock enabling * the dwc3-meson-gxl glue drivers handles "force mode switching" Remove all mach-meson gx & axg usb code and enable CONFIG_DM_USB_GADGET. Note: Only configs having both CONFIG_USB_DWC3_MESON_GXL=y *and* USB_GADGET_DWC2_OTG=y have been updated.
