From 4822114f4fb4328114da8ab199672656591a150d Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Sun, 20 Jun 2021 12:00:52 -0300 Subject: [PATCH] usb: ehci-mx6: Do not fail when 'reg' is not found Unlike imx6, on imx7 the USB PHY is described as: usbphynop1: usbphynop1 { compatible = "usb-nop-xceiv"; clocks = <&clks IMX7D_USB_PHY1_CLK>; clock-names = "main_clk"; #phy-cells = <0>; }; which does not have the 'reg' property. Do not return an error when the 'reg' property is not found for the USB PHY. This fixes USB gadget regression on a imx7s-warp board. Successfully tested the "ums 0 mmc 0" command on two boards: imx7s-warp and imx6dl-pico-pi.
