Subject: [PATCH 1/4] dt-bindings: connector: Add typec orientation switch properties
Date: Wed, 19 May 2021 15:14:47 +0800	[thread overview]
Message-ID: <1621408490-23811-2-git-send-email-jun.li@nxp.com> (raw)
In-Reply-To: <1621408490-23811-1-git-send-email-jun.li@nxp.com>

Typec orientation switch can be implementaed as a consumer of mux
controller, with this way, mux-control-name must be provided with
name "typec-orientation-switch", along with its 3 states value array
for none(high impedance), cc1, cc2.
