From 3922fb46f06035a246d31d25869a3276f1a1afa3 Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Tue, 15 Nov 2016 15:03:40 -0800 Subject: usb: dwc2: add amcc,dwc-otg support This patch adds support for the "amcc,usb-otg" device which is found in the PowerPC Canyonlands' dts. The device definition was added by: commit c89b3458d8cc ("powerpc/44x: Add USB DWC DTS entry to Canyonlands board") but without any driver support as the dwc2 driver wasn't available at that time. Note: The system can't use the generic "snps,dwc2" compatible because of the special ahbcfg configuration. The default GAHBCFG_HBSTLEN_INCR4 of snps,dwc2 can cause a system hang when the USB and SATA is used concurrently.
