[PATCH v3 13/14] staging: typec: fusb302: Hook up mux support using tcpc_gen_mux support

From: Hans de Goede
Date: Fri Sep 22 2017 - 14:39:09 EST


Add mux support to the fusb302 driver, call devm_tcpc_gen_mux_create()
to let the generic tcpc_mux_dev code create a tcpc_mux_dev for us.

Also document the mux-names used by the generic tcpc_mux_dev code in
our devicetree bindings.

Changes in v3:
-Drop devicetree bindings documentation, since this is only used with
device-properties set by platform code on X86/ACPI now, we don't need
bindings yet
