Subject: [PATCH 1/2] dt-bindings: phy: Allow defining the SATA AFE TX amplitude
Date: Wed, 30 Sep 2020 20:19:15 -0700 [thread overview]
Message-ID: <20201001031916.411999-2-f.fainelli@gmail.com> (raw)
In-Reply-To: <20201001031916.411999-1-f.fainelli@gmail.com>
Document a new property which allows the selection of the SATA AFE TX
amplitude in milli Volts. Possible values are 400, 500, 600 and 800mV.
