Subject: [PATCH 13/18] dt-bindings: usb: dwc3: Add Tx De-emphasis restrictions
Date: Sun, 11 Oct 2020 01:41:16 +0300 [thread overview]
Message-ID: <20201010224121.12672-14-Sergey.Semin@baikalelectronics.ru> (raw)
In-Reply-To: <20201010224121.12672-1-Sergey.Semin@baikalelectronics.ru>
In accordance with the driver comments the PIPE3 de-emphasis can be tunned
to be either -6dB, or -2.5dB or disabled. Let's add the de-emphasis
property restriction so the DT schema would make sure the controller DT
node is equipped with correct values.
