Subject: [PATCH v6 2/4] dt-bindings: usb: Add Qualcomm PMIC type C controller dt-binding
Date: Wed, 29 Jul 2020 00:13:38 -0700 [thread overview]
Message-ID: <20200729071340.7673-3-wcheng@codeaurora.org> (raw)
In-Reply-To: <20200729071340.7673-1-wcheng@codeaurora.org>
Introduce the dt-binding for enabling USB type C orientation and role
detection using the PM8150B. The driver will be responsible for receiving
the interrupt at a state change on the CC lines, reading the
orientation/role, and communicating this information to the remote
clients, which can include a role switch node and a type C switch.
