Subject: [PATCH 2/3] dt-bindings: usb: cdns,usb3: Add cdns,phyrst-a-enable property
Date: Tue, 25 Aug 2020 15:00:58 +0300 [thread overview]
Message-ID: <20200825120059.12436-3-rogerq@ti.com> (raw)
In-Reply-To: <20200825120059.12436-1-rogerq@ti.com>
Controller version 0x0002450D has USB2 PHY RX sensitivity issues
that needs to be worked around by enabling phyrst-a-enable bit
in PHYRST_CFG register.
There is no way to distinguish between the controller version
before the device controller is started so we need to add this
DT property.
