Subject: [PATCH 2/3] dt-bindings: usb: fusb302: Use usb-connector bindings for configuration
Date: Tue, 21 Aug 2018 13:28:22 +0100 [thread overview]
Message-ID: <6472fd66d20df31165f9645eb49f4f30a0a51468.1534853047.git.Adam.Thomson.Opensource@diasemi.com> (raw)
In-Reply-To: <cover.1534853047.git.Adam.Thomson.Opensource@diasemi.com>
There are now generic usb-connector bindings which can be used
to define a port controllers configuration for USB-PD, so device
specific bindings are no longer necessary.
This update deprecates 'fcs,operating-sink-microwatt', and references
the 'usb-connector' bindings instead to achieve the required port
config.
