Subject: [PATCH 1/4] dt-bindings: connector: Add typec orientation switch properties
Date: Mon, 22 Aug 2022 23:35:14 +0800 [thread overview]
Message-ID: <20220822153517.3747679-2-xu.yang_2@nxp.com> (raw)
In-Reply-To: <20220822153517.3747679-1-xu.yang_2@nxp.com>
Typec orientation switch can be implemented as a consumer of mux
controller. So we can use mux controller to control simple gpio switch
or other types of switch. This will cover the following typec switch
use case: High Speed, Super Speed and Sideband switch.
