Subject: [PATCH v2 2/9] usb: typec: mux: Add helpers for setting the mux state
Date: Mon, 24 Feb 2020 15:13:59 +0300 [thread overview]
Message-ID: <20200224121406.2419-3-heikki.krogerus@linux.intel.com> (raw)
In-Reply-To: <20200224121406.2419-1-heikki.krogerus@linux.intel.com>
Adding helpers typec_switch_set() and typec_mux_set() that
simply call the ->set callback function of the mux. These
functions make it possible to set the mux states also from
outside the class code.
