Subject: [PATCH v3 11/16] dt-bindings: usb: dwc3: Add Tx De-emphasis constraints
Date: Tue, 20 Oct 2020 14:20:56 +0300 [thread overview]
Message-ID: <20201020112101.19077-12-Sergey.Semin@baikalelectronics.ru> (raw)
In-Reply-To: <20201020112101.19077-1-Sergey.Semin@baikalelectronics.ru>
In accordance with the driver comments the PIPE3 de-emphasis can be tuned
to be either -6dB, -2.5dB or disabled. Let's add the de-emphasis
property constraints so the DT schema would make sure the controller DT
node is equipped with correct value.

Changelog v2:
- Grammar fix: "s/tunned/tuned"
- Grammar fix: remove redundant "or" conjunction.
