Subject: [1/3] usb: usb251xb: Add US lanes inversion dts-bindings
Date: Thu, 25 Apr 2019 00:12:05 +0300 [thread overview]
Message-ID: <20190424211208.17499-2-fancer.lancer@gmail.com> (raw)
Since a separate US ports lanes polarity inversion property is going to
be available the bindings doc-file should be updated with information
about swap-us-lanes bool property, which will be responsible for it.
