Subject: [PATCH v4 6/7] dt-bindings: usb: Add binding for fcs,fsa4480
Date: Sun, 6 Mar 2022 19:40:39 -0800 [thread overview]
Message-ID: <20220307034040.1111107-6-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <20220307034040.1111107-1-bjorn.andersson@linaro.org>
The Fairchild/ON Semiconductor FSA4480 Analog Audio switch is used in
USB Type-C configurations for muxing analog audio onto the USB
connector, and as such used to control the SBU signals for altmodes such
as DisplayPort.
Add a binding for this hardware block.
