From 4872d333a7e69cbfb10c3d9277f76e7572c924c1 Mon Sep 17 00:00:00 2001 From: Juan Gutierrez Date: Thu, 27 Oct 2016 16:29:48 -0500 Subject: MXSCM-212: mx6dqscm: usb: fix usb_otg_id iomux pad settings USB_OTG_ID iomux pad was missconfigured and not selecting the GPIO1 Alternative for QWKS and the ENET_RX_ERR for EVB, as a consequence when connecting a USB device the PWR_EN was disabled. So usb function like "usb start" was not working as it should.
