Subject: [PATCH v8 02/11] usb: typec: tcpci: Add set_vbus tcpci callback
Date: Mon, 21 Sep 2020 12:55:46 -0700	[thread overview]
Message-ID: <20200921195555.1050731-2-badhri@google.com> (raw)
In-Reply-To: <20200921195555.1050731-1-badhri@google.com>

set_vbus callback allows TCPC which are TCPCI based, however,
does not support turning on sink and source mode through
Command.SinkVbus and Command.SourceVbusDefaultVoltage.
