From 3db53374405fbf7a474086ed984189f65b6f0008 Mon Sep 17 00:00:00 2001 From: Serge Semin Date: Fri, 9 Apr 2021 14:30:27 +0300 Subject: usb: dwc3: qcom: Detect DWC3 DT-nodes using compatible string In accordance with the USB HCD/DRD schema all the USB controllers are supposed to have DT-nodes named with prefix "^usb(@.*)?". Since the existing DT-nodes will be renamed in a subsequent patch let's fix the DWC3 Qcom-specific code to detect the DWC3 sub-node just by checking its compatible string to match the "snps,dwc3". The semantic of the code won't change seeing all the DWC USB3 nodes are supposed to have the compatible property with any of those strings set.
