Subject: [PATCH v2 17/18] usb: dwc3: qcom: Detect DWC3 DT-nodes with "usb"-prefixed names
Date: Wed, 11 Nov 2020 12:15:51 +0300	[thread overview]
Message-ID: <20201111091552.15593-18-Sergey.Semin@baikalelectronics.ru> (raw)
In-Reply-To: <20201111091552.15593-1-Sergey.Semin@baikalelectronics.ru>

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 first make
sure the DWC3 Qualcomm driver supports them and second falls back to the
deprecated naming so not to fail on the legacy DTS-files passed to the
newer kernels.
