Subject: [PATCH 1/7] usb: typec: mux: Allow muxes to specify mode-switch
Date: Tue, 7 Jun 2022 19:00:19 +0000 [thread overview]
Message-ID: <20220607190131.1647511-2-pmalani@chromium.org> (raw)
In-Reply-To: <20220607190131.1647511-1-pmalani@chromium.org>
Loosen the typec_mux_match() requirements so that searches where an
alt mode is not specified, but the target mux device lists the
"mode-switch" property, return a success.
This is helpful in Type C port drivers which would like to get a pointer
to the mux switch associated with a Type C port, but don't want to
specify a particular alt mode.
